一种基于Windows界面的正电子湮没谱分析软件包

A Positron Annihilation Spectroscopy Analysis Program based on Windows Interface

在保留正电子寿命谱分析程序PATFIT和连续谱分析程序MELT主要优点的基础上研究开发了一个新的正电子湮没谱分析软件PASA。主要的改进包括:将PATFIT、MELT和多普勒展宽谱3种正电子湮没分析方法集成在Windows界面程序中,MELT程序脱离MATLAB环境独立运行;编写了完整的多普勒展宽谱分析程序,谱文件的读取、输入参数的调节和拟合结果的输出更加方便快捷,重点加强了正电子湮没实验谱和拟合结果的图形显示。介绍PASA软件的使用经验。

Based on the commonly used PATFIT and MELT program,a new program package —— Positron Annihilation Spectrum Analysis（PASA） with many user-friendly applications was developed.The main modifications are： three kinds of positron analysis methods（PATFIT,MELT,Doppler） were incorporated into PASA;MELT could run independently without being in MATLAB environment;Detailed Doppler analysis program were programmed into PASA.Experiences of using the PASA program were also introduced.
