Measurement of relative intensities of L‐shell x‐rays of some heavy elements using Cd‐109 radioisotope source

Abstract

Abstract The relative L‐shell x‐ray intensities of Sm, W, Ir, Au, Hg, Pb and U were measured using a Cd‐109 radioisotope source and a Si(Li) detector. The measured relative intensities were compared with the theoretically calculated values due to Scofield, computed for the present excitation energy of 22.6 keV. The experimental results were found to agree with theory in most cases.
