The resulting excitation functions of all 7 targets [only 5 shown here, where the experimental data are presented in the 2002 version of EXFOR – the two remaining reactions (on Pd-102 and Xe-124) have been also calculated and the excitation functions have been proposed, but not demonstrated as a plot today] have been prepared as ENDF files ready to be given to the IAEA NDS.
