Neutron sublibrary

The neutron sublibrary provides the evaluated nuclear data on neutron-induced reactions for 795 nuclides from H-1 to Fm-257 in the incident energy region from 10-5 eV to 200 MeV (partially 20 MeV). The data consist of nuclear reaction cross sections, neutron scattering angular distributions, energy-angle distributions of emitted light-particles and gamma-rays, and residual nucleus productions.

Feb. 2022: The upper limit of the unresolved resonance parameter of Pr-141 was inconsistent with that of unresolved resonance region. Fixed in update 1 (upd-1) on Feb. 16.
Corrected data (upd-1): n_059-Pr-141.dat.gz

May 2022: The upper energy limit of the photon production cross sections and energy spectra of 5 nuclides had been set to 20 MeV. Fixed in update 6 (upd-6).
Corrected data (upd-6): jendl5_upd6.tar.gz

The angle-energy distribution data of H-2 had been doubly given using LAW=6 and 7 above 20 MeV. Fixed in update 7 (upd-7).
Corrected data (upd-7): n_001-H-002.dat.gz
