✦ Synopsis
Title of program: EFYGA Nature of physical problem This program computes the interaction probability and the Catalogue number: ABBC counting efficiency of gamma photons in toluene scintillators for a given energy. Program obtainable from: CPC Program Library, Queen's University of Belfast, N. Ireland (See application form in this Method of solution issue) The Compton-electron distribution produced by the y ray-scintilator interaction is simulated by means of a Monte Computer: VAX 11/785; Installation: Centro de Cálculo, Carlo process. The counting efficiency is then computed by CIEMAT, Avda complutense 22, 28040 Madrid, Spain computing the efficiency for every point in the distribution and summing up to obtain the total efficiency. Operating system: VAX/VMS Restrictions on the complexity of the problem Programming language used: FORTRAN 77 None. High speed storage required: 15 kwords for the test run Typical running time The test requires about 10 mm of CPU time for a VAX 11/785 Number of bits in a word: 32 computer with the machine-independent random numbers generator. If the FORTRAN 'RAN' function is used in a VAX, No of lines in combined program and test deck: 522 the time is about 3 mm.
