Electron Interaction in Transition Metal X-ray Emission Spectra

Abstract

The Kβ1β' structure is investigated experimentally for all pure elements of the first transition series and for some of their compounds. Analogous structures are found for L emission spectra of some second transition series elements as well as of some lanthanides. Relative transition energies and probabilities are calculated in a frozen-orbital approximation for the transition from a normal K state to singly ionized states of the configuration 3p53dn4s2 for the elements Sc-Ni. The results support the interpretation that the Kβ1β' structure is due to the electron interaction between partially filled 3p and 3d subshells. The electron interaction mechanism also explains the effects in the heavier elements investigated.
