Abstract
A set of consecutively executed computer programmes have been developed for the quantitative interpretation of gamma ray spectra obtained with Ge(Li) detectors. The method compares spectral information with catalogued nuclear data and yields least squares fitted sets of activity which subsequently may be converted to parent masses. Results are presented for samples of unknown trace element composition and for spectra synthesized from the spectra of neutron irradiated high purity samples of elements and their oxides.
