Calculation of Neutron and Gamma-ray Production Cross Sections for Calcium from 8 to 20 MeV.


Book Description

Nuclear model calculations used for the previous evaluation for calcium (ENDF/B-V MAT 1320) lacked the effects of precompound particle emission. Experimental information now available suggests that these effects are significant from 8 to 20 MeV. Results of new calculations made to include such effects in all reaction cross sections from 8 to 20 MeV are presented. The resulting data set was prepared in the ENDF/B-V format and is referred to as Material 4152 Modification V in the DNA cross-section library.







Evaluation of 235U Neutron Cross Section and Gamma Ray Production Data for ENDF


Book Description

A discussion is given of the evaluation of neutron and gamma ray production cross sections of 235U from 10−5 eV to 20 MeV and the parts contributed by the author. All available new data are included in this evaluation, and the procedures adopted to assess the experimental data and adopt a set of recommended values are described. 22 figures, 10 tables.
