Relative strengths of the competing multipoles in the K and L series X-ray spectra in the NR limit

Abstract

For most of the transitions of the K and L series x-ray spectra the ratio of the contributions of the competing multipoles, δ², is independent of the radial matrix element in the non-relativistic limit. In the present paper calculations of δ² are made in the non-relativistic limit which give the relative strengths of the two closely competing electric and magnetic multipoles. The dominant mode in the emission processes of the transitions in the K andL series x-ray spectra has been assigned on the basis of these calculations.
