Nature of problem:
This program computes the interaction probability and the counting efficiency of gamma photons in toluene scintillators for a given energy.
The Compton-electron distribution produced by the gamma ray-scintillator interaction is simulated by means of a Montecarlo process. The counting efficiency is then computed by computing the efficiency for every point in the distribution and summing up to obtain the total efficiency.
The test requires about 10 m of CPU time for a VAX 11/785 computer with the machine-independent random numbers generator. If the FORTRAN 'RAN' function is used in a VAX, the time is about 3 minutes.
