M053900100011 METHOD (EXTB,SITA) The reaction yield curve measurement. M053900100012 DETECTOR (BF3) M053900100013 ANALYSIS (PLA) The Penfold-Leiss method for cross section M053900100014 unfolding from the yield curve. M053900100015 CORRECTION Above two-neutron reaction threshold the M053900100016 reaction (g,2n) cross section was calculated using M053900100017 the Weisskopf's formulae assuming a statistical M053900100018 decay of the GDR states. M053900100019 STATUS (CURVE) Data were compiled at the Russia MSU SINP M053900100020 CDFE by V.Varlamov. M053900100021 COMMENT The total photoneutron reaction (g,xn) cross sections M053900100022 were obtained for natural Al, S, Ta, Bi targets from M053900100023 thresholds to 30 MeV by directly counting of M053900100024 photoneutrons as a functions of bremsstrahlung M053900100025 energy. The (g,2n) reaction cross sections for Ta M053900100026 and Bi were calculated using the statistical theory M053900100027 of the GDR states decay and used to obtain the M053900100028 (g,sn) reaction cross sections for these nuclei.
