In addition, we revealed that the same and similar problems occurred the data in other 73 nuclei FENDL-3.1d selected from TENDL- 2010 or TENDL-2011. Thus, we revised the yield data and verified that the sharp spike just above 20 MeV in the DPA cross-section disappeared using the revised data. Moreover, the DPA cross-section data of 49 nuclei in FENDL-3.1d from JENDL/HE-2007 became much smaller sharply above 20 MeV because the nuclei had no energy distribution data of residual nuclei above 20 MeV. Other problems occurred in 13 nuclei of FENDL-3.1d from JEFF-3.1.1 above several MeV, due to wrong energy distribution data of recoil nucleus in the inelastic scatter- ing to continuum states below 20 MeV and no energy distribution data of residual nuclei above 20 MeV. The DPA cross-section data of more than 70% of nuclei in FENDL-3.1d have problems due to non-physical data in the original nuclear data.}, pages = {344--351}, title = {Problems of DPA cross-sections above 20 MeV in FENDL-3.1d found in A-FNS neutronics analysis}, volume = {57}, year = {2019} }
