Program system for analysing positron lifetime spectra and angular correlation curves

Title of program: PATFIT Catalogue Id: AANN_v1_0 Nature of problem In the field of positron annihilation research two of the experimental methods used are positron lifetime and angular correlation measurements. In both cases a measured spectrum normally consists of a sum of several components. The experimenter wants to extract from the spectra characteristic parameters for each component.
