本文详细讨论了符合相加修正方法并给出计算公式。用~(152)E_u,~(133)Ba,~(75)Se,~(60)Co,~(22)Na,~(86)Y,~(134)Cs,~(137)Cs,~(57)Co,~(241)Am,~(203)Hg,~(54)Mn,~(88)Cd,~(139)Ce 十四种核素的γ参考源,分别在源与晶体表面距离为0.95,3.0,11.56,16.75 cm 下,刻度了 G_e(Li)探测器的峰效率,给出了不同距离下总效率的计算值和实验值、符合相加修正系数、全能峰效率、峰效率拟合公式及其拟合优度。在59.6—1408keV 能区内,全能峰效率的不确定度为0.8—1.6%,还讨论了峰效率测最中的误差来源及其大小。
This article discusses in detail the method of adding and correcting and gives the formula. The effects of ~ (152) E_u, ~ (133) Ba, ~ (75) Se, ~ 60Co, ~ 22 Na, ~ 86 Y, ~ 134 Cs, ~ 137 Cs, Γ reference sources of fourteen nuclides of Co, ~ (241) Am, ~ (203) Hg, ~ (54) Mn, ~ (88) Cd and ~ The peak efficiencies of the G_e (Li) detector are calibrated at distances of 0.95, 3.0, 11.56 and 16.75 cm, and the calculated and experimental values of the total efficiencies at different distances are given, which are in accordance with the additive correction factor, Efficiency fitting formula and its fitting goodness. In the 59.6-1408 keV energy range, the uncertainty of the omnipotent peak efficiency is 0.8-1.6%. The source of error and its magnitude, which is the most significant peak efficiency measure, are also discussed.
