摘要

正电子在某些材料中的寿命与现有仪器的时间分辨率很接近，要从这些材料的实验数据中得到寿命的正确结果，一定要考虑仪器的分辨函数。为此调试了Positronfit-Extended程序

[1，2]

（简称P-E程序）和编排了提供近似分辨函数的程序，并用这组程序探讨了以近似分辨函数代替仪器精确分辨函数的可能性。

Abstract

A program is presented to fit the resolution function spectra which are discribed as a sum of Gaussians. By the program we have determined the approximate parameters of the resolution function which are needed in the convolution model of the POSITRONFIT-EXTENDED program. The possibility of replacing a real resolution function with a approximate one in the analysis of the positron lifetime spectra has been discussed.
