本文报告了直径一定的圆柱形体积可变的样品Ge(Li)γ谱分析方法。该方法的特点是用实验方法确定各种γ射线能量的全能峰效率随样品体积(厚度或重量)的变化关系。从而避免了制备各种不同样品量的标准刻度源,解决了实际中看来非常困难的问题。
In this paper, a method of Ge (Li) γ spectroscopy analysis of a cylindrical sample with variable volume is reported. The method is characterized by experimentally determining the all-rounder peak efficiency of various gamma-ray energies as a function of sample volume (thickness or weight). This avoids the need to prepare standard scale sources of various sample sizes and solves problems that appear to be very difficult in practice.
