PALSfit: A new program for the evaluation of positron lifetime spectra

PALSfit is a new Windows program for the analysis of positron lifetime spectra. PALSfit combines into one interactive Windows program the features of our previous PATFIT program package, such as data input, least-squares fitting routines as well as graphical displays. A number of options are available, including constraints on positron lifetimes, intensities, background and area, and corrections for annihilation in the positron source. In addition, a number of new features have been included. The Windows user-interface makes to a large extent the various features of the program self-explanatory, and using the program is straightforward. (© 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
