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 GeLi 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
