Measurements of radiative vacancy transfer probabilities from L 3 subshells to M, N and O shells and subshells in the atomic range 72⩽ Z⩽92

Abstract

The probabilities of vacancy transfer, η L3M, ηL 3M 1, ηL 3M 4, ηL 3M 5, η L3N, ηL 3N 1, ηL 3N 4, ηL 3N 5, ηL 3O 1 and ηL 3O 4,5 from L 3 subshell to M, N and O shells and subshells for the elements Hf, Ta, W, Re, Pt, Au, HgO, Tl, Pb, Bi, Th, U have been measured using L shell fluorescence yields and X-ray intensity ratios. These experimental values were obtained from samples excited by 59.5-keV γ-rays, which were emitted from an 241Am radioisotope source. Also K and L X-rays emitted from samples were measured by means of Si(Li) detector with a resolution of 155 at 5.9 keV. The results obtained from this study are compared with the results of other studies.
