Digital methods of photopeak integration in activation analysis.

A study of the precision attainable by several methods of gamma-ray photopeak integration has been carried out. The 'total peak area' method, the methods proposed by Covell, Sterlinski, and Quittner, and some modifications of these methods have been considered. A modification by Wasson of the total peak area method is considered to be the most advantageous due to its simplicity and the relatively high precision obtainable with this technique. A computer routine for the analysis of spectral data from nondestructive activation analysis experiments employing a Ge(Li) detector-spectrometer system is described.
