Interactive positronfit: A new version of a program for analysing positron lifetime spectra

Title of program: INTERACTIVE POSITRONFIT Catalogue Id: AAHI_v1_0 Nature of problem Positrons annihilate in condensed matter from different states (e.g., from defect traps in metals) so that a measured lifetime spectrum consists of a sum of exponential decay components smeared with the instrumental resolution function and superimposed on a constant background. Experimenters want to extract the lifetimes and intensities of the annihilation from different states.
