摘要
介绍了γ谱分析中的γ—γ级联辐射的符合相加校正的两种方法的原理及相应的计算表达式,并对它们作了评价。通过比较可知,不考虑级联γ辐射角关联的符合相加效应的校正方法通常不应采纳.
Two correction methods were introduced and evaluated for coincidence summing effect of γ-γ cascade radiation in γspectrometry. It is concluded that the method in which the angular correlation of γ-γ cascade radiation is ignored should not be adopted in general.
