Evaluation of neutron nuclear data of Praseodymium-141 and -143

For the next version of JENDL general purpose file, neutron nuclear data on $$^{141,143}$$Pr are evaluated considering cross sections and spectra provided from experiments in the fast neutron energy region up to 20 MeV. Total cross section is derived from optical model. Pre-equilibrium and direct-reaction processes are taken into account in addition to the compound process. The statistical model is applied to calculate the cross sections above the resolved resonance region. For unstable $$^{143}$$Pr nuclide having less experimental data, we use the same optical potential as $$^{141}$$Pr. The resolved resonance parameter remains unchanged from JENDL-4.0. The present evaluations are consistent with experimental data, reflecting new measured one. The evaluated data are compiled into an ENDF-formatted data file for the next version of JENDL.
