Nature of problem:
Analysis of positron lifetime spectrum assuming a non-Gaussian spectrometer resolution function.

Solution method:
Least-squares technique.

Restrictions:
Two expotentials required for the prompt, a maximum of three allowed in the spectrum. No independent source correction is included.

Running time:
Analysis of a typical lifetime spectrum requires about 20 s of CPU time on the PDP 10.
