摘要

【正】 The cross sections of long-lived radionuclides of importance in fusionreactor technology are measured by activation method for ¹³⁷Ba（n,p）¹³⁷Cs,¹⁸²W（n,n’x）¹⁷⁸Hf^m2 and ¹⁹³Ir（n,2n）¹⁹²Ir^m2 reactions at 14 MeV.The neutron fluencesare determined by the cross sections of ⁹³Nb（n,2n）⁹²Nb^m,⁵⁴Fe（n,x）⁵¹Cr and⁵⁴Fe（n,p）⁵⁴Mn reactions.The induced gamma ray activities of the irradiated Ba₂O₃,Wand Ir samples and their monitor foils are measured by a calibrated Ge（Li）detector oran anti-Compton gamma ray spectrometer.
