Abstract : High-energy bremsstrahlung, variable up to about 60 MeV, from high-intensity electron linacs can produce activation through a variety of photonuclear reactions. A great range of activities by half-lives can be used. Some discrimination between target elements can be obtained through the choice of bremsstrahlung endpoint energy. The high discrimination of Ge(Li) gamma-ray spectrometers permits much of the analysis to be accomplished without chemical separation of resulting nuclei; hence nondestructive analysis can be applied to many materials. To facilitate the use of such analysis, a compilation of photonuclear reactions with their resulting gamma-rays has been prepared, consisting of two tables. Table 1 lists the photonuclear reactions by target nuclei, giving the residual nuclei for half-lives from 100 micro sec to 24 hours. Table 2, derived from Table 1, is a list of gamma-ray energies by reactions designed to identify unknown target nuclei. (Author)
