Measurements of radiative vacancy transfer probabilities from L3 subshell to M and N subshells of Sm and Eu in halogen compounds

Abstract

The radiative vacancy transfer probabilities from the L3 subshell to the M and N subshells for Sm and Eu and their compounds have been measured using L shell fluorescence yields and X-ray intensity ratios. The samples were excited by 59.5 keV γ-rays, which were emitted from an Am-241 radioisotope source. The L X-rays emitted from samples were counted by a Si(Li) detector with a resolution of 155 eV at 5.9 keV. The experimental values were compared with the calculated theoretical values for pure Sm and Eu.
