Final RCM on Therapeutic Radionuclides, IAEA, May/June Results calculated and prepared as ENDF files. (One file received from Choi). But:

Final RCM on Therapeutic Radionuclides, IAEA, May/June Unsolved EMPIRE problems: What is the origin of the differences between TALYS and EMPIRE, if they are so similar? GCASC does not work (spectra with GCASC=1 are identical to those =0) DEGAS not used for gammas. Why (and how to correct it?) Why the nonphysical sharp decrease above 18 MeV?

Final RCM on Therapeutic Radionuclides, IAEA, May/June CONCLUSIONS Pre-eq.  emission useful to describe cross sections and  spectra, if one is not just in double-magic region. Therein, DSD (or CDSD) model is more reliable. Physically both describe the same situation with emphasis on different aspects of the reality. Two released “do-all” nuclear codes TALYS and EMPIRE give similar results away of closed shells. In their vicinity, there is no clear preference of either of the codes which might be universally valid.
