Abstract
The combination of photon activation and solid state γ-ray detection provides a very effective method of analysis of rare earths. The present report describes the production rates of almost all of the product nuclides found in yttrium and 14 rare earths irradiated with 70 MeV bremsstrahlung photons from an electron synchrotron. A 20 cm3 lithium-drifted germanium diode was used as a detector. Sensitivities of this method have been summarized for photon activation analysis, and experimental reaction yields have been obtained in order to discuss the reactivity of high-energy photons with nuclei in the rare earth region.
