A computer program for analysing positron lifetime spectra
A Windows based computer program PALSfit has been developed for analysing positron lifetime spectra. The program is built upon the well tested PATFIT package. The present document describes the mathematical foundation of the PALSfit model as well as a number of features of the program. The two cornerstones in PALSfit are the following least-squares fitting modules: PositronFit, which extracts lifetimes and intensities from the measured lifetime spectra, and ResolutionFit, which determines the time resolution function from lifetime spectra that have been recorded for this purpose. The PALSfit software is available from Risø DTU (www.palsfit.dk ). At this web-site there are also links to test examples and hands-on description of the windows interface.
