PATFIT-88: A DATA-PROCESSING SYSTEM FOR POSITRON ANNIHILATION SPECTRA ON MAINFRAIME AND PERSONAL COMPUTERS

A data processing system has been developed for analyzing positron annihilation lifetime and angular correlation spectra on main- frame and Personal Computers (PCs). The system is based on the PATFIT programs previously developed for use on mainframe computers. It con- sists of the three fitting programs POSITRONFIT, RESOLUTION and ACARFIT and three associated programs for easy editing of the input data to the fitting programs, as well as a graphics program for the display of measured and fitted spectra. They can be used directly on any IBM- compatible PC. The PATFIT-88 software is available from Riso National Laboratory.
