Problem on gammas emitted in capture reaction of TENDL-2019 and JEFF-3.3

Konno, Chikara  ; Kwon, Saerom*

We found that a lot of nuclei in TENDL-2019 had no high-energy gamma peaks in secondary gamma spectra from the capture reaction and several nuclei in JEFF-3.3 also have. This problem causes not only drastically small damage energy production cross sections for radiation damage calculations at incident neutron energies below a few keV but also smaller gamma productions in shielding calculations. The problematic energy distribution data for secondary gammas in TENDL-2019 and JEFF-3.3 should be revised.
