Precision measurements of gamma-ray intensities. II. 152Eu, 154Eu and 192Ir

Abstract

Relative intensities of gamma rays in the decay of 152Eu, 154Eu and 192Ir were measured precisely with a calibrated Ge(Li) detector. Errors of relative intensities for strong gamma rays are 0.3–0.5%. These multi-gamma-ray sources are useful for the calibration of the Ge(Li) detector. Gamma-ray intensities per decay of 192Ir were derived from the relative intensities.
