A new method was developed for analysing the positron lifetime spectra on the graphical display screen of an IBM PC. The multi-exponential function model was used and the lifetime components of the spectrum were stripped one by one from the longest to the shortest while the graphics on the display screen were changing correspondingly. The obtained initial parameters of a lifetime spectrum are efficient and good enough to be used by the IBM PC (Professional) POSITRONFIT Program as input data.
