POSITRONFIT: A versatile program for analysing positron lifetime spectra
datasetposted on 06.12.2019 by Peter Kirkegaard, Morten Eldrup
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
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)
