PFPOSFIT: A new version of a program for analysing positron lifetime spectra with non-Gaussian prompt curve

Title of program: PFPOSFIT
Catalogue Id: ACKX_v1_0

Nature of problem
A measured positron lifetime spectrum consists of a sum of exponential decay components smeared with the instrumental resolution function. Experimenters want to extract the life times and intensities of the different components.
