X-ray and gamma-ray intensity measurements in 131I, 166Ho, 198Au and 199Au decays

Abstract

Relative intensities of X- and gamma rays emitted in the decays of 131I, 166Ho, 198Au and 199Au have been measured precisely using a set of five detectors: 96.0 cm 3 and 57.1 cm 3 coaxial HPGe detectors, a 28.27 mm 2 × 5.0 mm vertical planar HPGe detector and two 28.27 mm 2 × 5.5 mm Si(Li) detectors. The measured values of X-ray intensities are, in general, in good agreement with the theoretically calculated values. The intensities of different components of K and L X-rays in the above mentioned decays have been measured for the first time.
