Show Abstract
Subramanian “Ram” Raman, a distinguished nuclear physicist and senior staff member of the Physics Division at Oak Ridge National Laboratory (ORNL), died April 8, 2003. In June 1966, Raman joined the staff at ORNL working in the Nuclear Data Project. This position provided him insights into important open questions in nuclear structure physics, and the power of “horizontal” compilations of properties across a broad range of nuclei. These insights would guide Raman’s research interests throughout his 36‐year career at ORNL.
As shown by his great variety of publications, Raman’s research career was marked by an intense interest in all areas of nuclear physics. He published papers on topics ranging from detailed nuclear structure to giant resonances, to the search for superheavy nuclei, to the scattering of heavy ions. His research resulted in over 200 published papers and over 3000 citations of his work. It is however, his nuclear data evaluations, both horizontal and vertical, that we most often remember. His most often cited papers deal with the evaluation and systematics of nuclear data, and he helped establish many of the “rules” and guidelines for assignment of nuclear level properties. An overview of Raman’s work at ORNL is presented. © 2005 American Institute of Physics

Show Abstract
One of the signature features of Raman’s work was the love and exploitation of nuclear systematics as a tool to discern interesting structural phenomena and to understand better the evolution of structure with nucleon number. Such a tool, properly used, can be extremely powerful, especially when data are correlated with a physically meaningful variable that yields simple and compact trajectories. It can reveal trends that reflect basic elements of nucleonic interactions, it can reveal nuclei with special symmetries, or anomalous nuclei, and it can point to possibly incorrect measurements. We focus on several uses of correlations of nuclear data, illustrating the above ideas. Particular aspects are proton‐neutron interactions, quadrupole collectivity, the search for phase transitional behavior and critical point nuclei, and a new mapping of collective nuclear structure across large parts of the nuclear chart, leading to a discovery of an “arc of regularity” characterizing certain nuclei while others nearby in Z and N exhibit chaotic spectra. © 2005 American Institute of Physics

Show Abstract
This paper broadly covers key events and activities from which the Department of Energy Nuclear Criticality Safety Program (NCSP) evolved. The NCSP maintains fundamental infrastructure that supports operational criticality safety programs. This infrastructure includes continued development and maintenance of key calculational tools, differential and integral data measurements, benchmark compilation, development of training resources, hands‐on training, and web‐based systems to enhance information preservation and dissemination. The NCSP was initiated in response to Defense Nuclear Facilities Safety Board Recommendation 97‐2, Criticality Safety, and evolved from a predecessor program, the Nuclear Criticality Predictability Program, that was initiated in response to Defense Nuclear Facilities Safety Board Recommendation 93‐2, The Need for Critical Experiment Capability. This paper also discusses the role Dr. Sol Pearlstein played in helping the Department of Energy lay the foundation for a robust and enduring criticality safety infrastructure. © 2005 American Institute of Physics

Show Abstract
The process of particle emission in the pre‐equilibrium stage has a very important contribution in this energy region and several approaches have been proposed to explain it. Their prediction power must be tested using comparison with the data for a variety of configurations. Calculations have been done using the exciton model and two main approaches proposed to improve its predictive power for complex particle emission. Data reported in this work allow the extension to higher energies of databases that are now limited to energies around 60 MeV. Together with other experimental results available in the literature they allow a more global view on the capabilities of each approach. © 2005 American Institute of Physics

Show Abstract
The nuclear Ramsauer model is a semi‐classical, analytic approximation to nucleon‐nucleus scattering that reproduces total cross‐section data at the 1% level for A > 40, En = 5–60 MeV with 7–10 parameters. A quick overview of the model is given, demonstrating the model’s utility in nuclear data evaluation. The Ramsauer model predictions for reaction cross section, elastic cross section, and elastic scattering angular distributions are considered. In a recent paper it has been shown that the nuclear Ramsauer model does not do well in predicting details of the angular distribution of neutron elastic scattering for incident energies of less than 60 MeV for 208Pb. However, in this contribution it is demonstrated that the default angular bin dispersion most widely used in Monte Carlo transport codes is such that the observed differences in angular shapes are on too fine a scale to affect transport calculations. Simple studies indicate that 512–2048 bins are necessary to achieve the dispersion required for calculations to be sensitive to the observed discrepancies in angular distributions. © 2005 American Institute of Physics

We present work on the N − N and 7Li systems that is relevant to the international effort to re‐evaluate the neutron standard cross sections. The R‐matrix analysis of the N − N system also determined the n‐p capture cross section for use in BBN modeling of light‐element abundances in the early universe with an uncertainty of less than 2.5 %. The R‐matrix results for the 6Li(n,t)4He cross section agree qualitatively with a microscopic RRGM calculation that uses semi‐realistic N‐N potentials. However, they disagree with some cross‐section measurements for the reaction, and with another evaluation. © 2005 American Institute of Physics

A new evaluation of all‐important neutron cross sections of the stable isotopes of Ti was performed in the neutron energy range 0.2–20 MeV, which is the whole energy range above the resonance region. The evaluation combines the results of recent nuclear model calculations (prior) and the complete existing experimental database by means of the Bayesian code GLUCS03 in order to obtain the most accurate description of the cross sections (posterior) within our present knowledge. The evaluation of the total cross section is completely based on the accurate experimental database for natural Ti. The results of the evaluation, files 3 (cross sections) and files 33 (cross‐section covariances) for all stable isotopes of Ti will be part of the new isotopic evaluations for Ti for the Joint European Fission and Fusion (JEFF) file. © 2005 American Institute of Physics

Show Abstract
An evaluation of the 232Th neutron total and capture cross sections has been performed in the energy region between 4 keV and 140 keV. The evaluation results from a simultaneous analysis of capture, transmission, and self‐indication measurement data, including the most recent capture cross‐section data obtained at the GELINA facility of the Institute for Reference Materials and Measurements at Geel (B) and at the n‐TOF facility at CERN (CH). The experimental data have been analysed in terms of average resonance parameters exploiting two independent theoretical approaches — the Characteristic Function model and the Hauser‐Feshbach‐Moldauer theory. The resulting parameters are consistent with the resolved resonance parameters deduced from the transmission measurements of Olsen et al. at the ORELA facility. © 2005 American Institute of Physics

Rhodium‐103 is a prominent fission product in nuclear reactors as well as a usual detector in fast neutron activation or dosimetry techniques. The neutron‐induced reactions and the energy regions of interest differ significantly depending on the applications. In this paper, a new evaluation spanning the 0‐ to 30‐MeV energy range is described. The quality of the transitions between the various energy intervals was assessed with the help of statistical techniques to test the resonance parameter distributions and the SPRT method to check optical model calculations. The evaluated nuclear data file was verified and processed. The quality of the data was successfully tested against both differential and integral results for activation, thermal and fast reactor applications. This new file should be part of the upcoming JEFF‐3.1 library. © 2005 American Institute of Physics

Show Abstract
A research and development (R&D) project on a nuclear data processing and utilization system was started in 2002 for a five‐year plan for innovative nuclear energy systems such as innovative reactors and accelerator‐driven systems. The nuclear data processing and utilization system is being developed to use on a PC‐Linux server through the Internet, so that it has a graphic user interface (GUI) in order to easily utilize the system for various nuclear design studies in the innovative reactor development. The nuclear data processing and utilization system, which is able to handle JENDL‐3.3, ENDF/B‐VI, and JEFF‐3 to generate point‐wise and group‐wise cross sections in several formats, has the capability to perform criticality and shielding benchmarks. A prototype system was developed in order to examine the operability of the user interface and discuss detailed specifications of the system. The system is expected to be a verification tool of nuclear data for development of innovative nuclear reactors, because cross‐section generation with nuclear data and the various benchmarks for criticality and shielding problems can be easily performed. © 2005 American Institute of Physics

Show Abstract
A new evaluated nuclear data library has been created. The library consists of two sub‐libraries for neutron and proton incident particles. The first version of neutron sub‐library has been completed and described in the present paper. The library contains nuclear data for transport, heating, and shielding applications for 242 nuclides ranging in atomic number from 8 to 82 in the energy region of primary neutrons from 10‐5 eV to 150 MeV. Data below 20 MeV are taken mainly from ENDF/B‐VI (Revision 8) and for some nuclides, from the JENDL‐3.3 and JEFF‐3.0 libraries. The evaluation of emitted particle energy and angular distributions at the energies above 20 MeV was performed with the help of the ALICE/ASH code and the analysis of available experimental data. The total cross sections, elastic cross sections, and elastic scattering angular distributions were calculated with the help of the coupled channel model. The results of the calculation were adjusted to the data from ENDF/B‐VI, JENDL‐3.3m or JEFF‐3.0 at the neutron energy equal to 20 MeV. The library is written in ENDF/B‐VI format using the MF=3/MT=5 and MF=6/MT=5 representations. © 2005 American Institute of Physics

Show Abstract
The evaluated intermediate‐energy activation cross‐section library IEAF‐2001 has been tested against integral experiments with SS‐316 and F82H steels exposed to a white neutron flux spectrum extending up to 55 MeV. By making use of the ALARA inventory code the expected γ‐active product nuclide inventories were calculated and compared with the measured one. It was found that IEAF‐2001 reasonably agrees with experimental data for most of the detected radioisotopes. The reasons for some larger disagreements were found to be the uncertainty of the sample elemental composition, non‐validated neutron activation reaction cross sections, and sequential charge particle reactions. © 2005 American Institute of Physics
