To: research1@pi.net cc: A.Pashchenko, R.Forrest March 6, 1996 Dear Jura; I finished all tests of my evaluations for Ho-165(n,g) and Ir-191(n,g). But it was surprise for me that the isomer production cross sections obtained are very close to your evaluations included in EAF-4. After more careful analysis I have found that your evaluations based on the energy dependent isomer ratios normalized to the thermal data. It is very close to our recommendations discussed in my contribution to the S.Petersburg Meeting. It is very pity that you said me nothing about this approach before. Were your approach is published? I will be happy to get a corresponding copy of your preprint or publication on this subject. In any case I need the reference on your work to include it in the final report on the LLRN CRP. Please send the reference as soon as possible. Your energy dependence of isomer ratios differs only a little from the similar one that we attempted to prepare with M.Chadwick at Livermore (he was not informed about your approach too!). We shall try to develop more accurate systematics of the isomer ratios for the radiative capture and I will be happy to discuss our approach with you during the Madrid Meeting on this May. But now I don't see a necessity to send our evaluations of the (n,g) reactions as a contribution to FENDL/A-2. I am agree that the EAF-4 data for these two reactions are good enough and our changes relates to the energy region above 1 MeV where we have no any experimental data. It is open question what must be recommended for the final report of the LLRN CRP. I hope to find some a compromise on this subject after discussions with you and A.Pashchenko. Looking forward to hear your replay on my former message sent on today morning. Best regards, Anatoly
