A computer program has been worked out for the following requirements: (1) The program is to render a listing of the elements
detected, together with their respective concentrations, not just an evaluation of the gamma-spectrum (peak energies and areas).
(2) There should be no necessity to intermediate decisions, i.e. execution of the program should be possible by auxiliary
personnel. (3) Gamma-ray spectra recorded under widely different conditions should be amenable to evaluation. This implies
a large range of variation of the number of channels per peak. (4) In order to have the most extensive capability of executing
multi-element analyses instrumentally, it must be possible to evaluate complex spectra with many superpositions. The program
involves the fitting of Gaussians. It is shown that this evaluation method gives more precise peak area determinations than
the summation method and also yields reasonable results in the case of strong superposition.
