Abstract

A new method for checking the goodness-of-fit in gamma spectroscopy in proposed. Theoretical calculations are verified with the installation of the new formula into a gamma spectrum analysis program SAMPO78. The new method is clearly shown to be more sensitive in detecting irregular peak shapes and unsatisfactory fitting results than the usual χ2 per degrees of freedom test.

一种测定伽马能谱拟合优度的新方法
提出了一种检验伽马能谱拟合优度的新方法。将新公式安装到伽马谱分析程序SAMPO78中,验证了理论计算。新方法在检测不规则峰形和不理想拟合结果方面比常用的每自由度χ2检验更灵敏。
