Photonuclear Activation Analysis with Ge(Li) Detectors - Compilation II.
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 resolution 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, supplementing the compilation for activities with half-lives from 100 microsec to 24 hours given in NRL Report 7554. This second compilation is for activities with half-lives from 24 hours to 1 year and again consists of two tabulations. Table 1-S list the photonuclear reactions by target nuclei. Table 2D and 2E, the final two parts of Table 2, list the reactions by gamma-ray energies: Table 2D is for half-lives from 24 hours to 30 days, and Table 2E is for half-lives from 30 days to 1 year.
