Resolution of Time-Dependent Gamma Spectra with a Digital Computer and Its Use in Activation Analysis

Recent developments in activation analysis emphasize completely instrumental methods employing -ray spectrometry. For such analyses data handling is a problem. To make better use of the obtainable data a small electronic digital computer was programmed to correct, normalize, and resolve time dependent spectra from short-irradiationtime neutron-activation samples. Its use permits obtaining maximum information from mixed spectra and freedom from simultaneous irradiation of elemental standards. Typical analyses using 5- min irradiations are given and the peeling technique used is described. Reference spectra were collected and are available for 69 elements. (auth)
