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. Versions of this program held in the CPC repository in Mendeley Data AAHI_v1_0; INTERACTIVE POSITRONFIT; 10.1016/0010-4655(78)90084-X This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
