Status and evaluation methods of JENDL Fusion File and JENDL PKA/KERMA File

Analysis ofn+6Li Reactions Using the Continuum-Discretized Coupled-Channels Method

“…2,3) In spite of the importance of the n + 6 Li reaction as described above, experimental data leading to continuum breakup processes are extremely rare, especially for the neutron energy region above 20 MeV.…”

“…The method explained above cannot be applied to light nuclei, namely, 2 H, 6,7 Li, 9 Be, 12 C, 14 N and 16 O, due to the nature of the modeling which assumes statistical properties. Therefore we adopted the pseudo-level representation for Li, C and N, and cross sections and angular distributions of the pseudo levels were adjusted to reproduce the measured neutron DDX data.…”

“…1,2 H, 6,7 Li, 9 Be, 12 C, 14 N, 16 O, 19 F, 27 Al, natural, 28,29,30 Si,natural,40,42,43,44,46,48 W, natural,204,206,207,208 Pb and 209 Bi. Here, the superscript numbers denote the mass number, and "natural" denotes that the data for natural element are constructed.…”

“…The γ -ray production data of JENDL-3.1 were revised for JENDL-3.2 in parallel to JENDL Fusion File project, and the results were adopted in JENDL Fusion File for the following nuclei; 6,7 Li, 9 Be, 12 Pb and 209 Bi. In order to contain the DDXs of secondary charged particles, the ENDF-6 format 8) was adopted in compiling JENDL Fusion File.…”

“…Details of the evaluation methodology are described in Ref. 9) and the descriptive part of the evaluated library (MF=1) for each nucleus, so a simple explanation of the evaluation method is given in this paper. However, in order for this paper to be reasonably self-contained, it was inevitable to have some overlap with Ref.…”
