Neutron- and proton-induced cross-section data are required in a wide energy range beyond 20 MeV, for the design of accelerator applications. New evaluations are performed with recent knowledge in the optical and pre-equilibrium model calculations. We also evaluated cross-sections for p+Li and p+
Be which have been highly requested from a medical field. The present high-energy nuclear data library, JENDL-4.0/HE, includes evaluated cross-sections for incident neutrons and protons up to 200 MeV (for about 130 nuclei). We overview substantial features of the library, i.e., (1) systematic evaluation with CCONE code, (2) challenges for evaluations of light nuclei and (3) inheritance of JENDL-4.0 and JENDL/HE-2007. In this talk, we also focus on the results of benchmark calculation for neutronics to show performance of the present library.

Times Cited Count:1 Percentile:11.58(Physics, Multidisciplinary)Applicability of the pre-equilibrium coalescence model was investigated toward advanced nuclear data. This study was devoted to the analysis for nucleon-induced alpha-particle production cross sections up to 200 MeV. The optical model calculation was performed with suitable potential parameters both for incident- and outgoing- channels. The Iwamoto-Harada-Sato coalescence model was tentatively incorporated into the GNASH code in order to take account the pickup contribution from the pre-equilibrium stages. It was found that the present approach can reproduce measured cross sections better than empirical models which had been commonly used for nuclear data evaluations up to 100 MeV. From comparisons between the model calculations and measurements, we discuss the behaviors of the model parameters and applicability limit of the present approach.

Light-ion production cross sections should be evaluated to estimate irradiation damage of the structural materials and soft-error of semiconducting devices. However, the evaluations have strongly relied on some empirical models. We had introduced pre-equilibrium coalescence model for the cross section analysis, and already confirmed its validity. In this work, multi-particle light-ion emission process was taken into account. We will present the computational results in this conference.
