Title of program: POSITRONFIT Catalogue Id: AAGK_v1_0 Nature of problem In a condensed material positrons may annihilate at several different characteristic rates. A measured positron lifetime spectrum will therefore consist of a sum of decaying exponential functions with different decay rates, smeared somewhat owing to the finite time resolution of the measuring system and superimposed on a constant background. Versions of this program held in the CPC repository in Mendeley Data AAGK_v1_0; POSITRONFIT; 10.1016/0010-4655(72)90070-7 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
