Abstract

A brief description is given of the most recent version of the PALSfit3 program. Based on previous programs (PALSfit and PATFIT) which have been used by a number of positron annihilation groups, PALSfit3 has been extended to include the option of log-normal broadening of the lifetime components. In addition more detailed graphics output has been added, and the possibility to select output in spread sheet format included. A special feature is the possibility to exclude certain channel ranges in a lifetime spectrum from the analysis, which may be valuable if spectra contain ”bumps”, for example due to scattered positrons in beam experiments. Details of PALSfit3 can be found on the PALSfit web page (www.palsfit.dk).
