The 3263600100015 efficiency was calibrated with a series of standard 3263600100016 gamma sources provided by China Institute of Atomic 3263600100017 Energy. 3263600100018 METHOD (FPGAM) The direct gamma ray spectrometry method was 3263600100019 used for measuring most fission products in this work. 3263600100020 (CHSEP,GSPEC) For the long half-life fission products 3263600100021 Ru-103,Ru-106,Sb-125 and Cs-137. the yields were 3263600100022 determined by chemical separation followed by gamma 3263600100023 ray spectrometry. 3263600100024 CORRECTION Corrections were made for gamma self-absorption in the 3263600100025 sample. In the gamma energy range of considered 3263600100026 fission products, the correction factor was 0.89-1.0. 3263600100027 DECAY-DATA The decay data given below were used for calculating 3263600100028 the fission yields.
