Nature of problem:
Analysis of positron lifetime spectra, cf description of the original version of POSITRONFIT.

Solution method:
Least-squares technique.

Restrictions:
Maximal seven gaussian components in the resolution curve. Other restrictions as in Comp. Phys. Commun. 3(1972)240.

Running time:
The analysis of a single, typical lifetime spectrum takes about 85 s on the B 6700 (or about 12 s on the IBM 370/165).
