Abstract

The soft-x-ray L2,3 emission and absorption spectra of Mg metal have been determined by means of high-resolution ab initio augmented-plane-wave calculations. The inclusion of transition-matrix elements calculated from the augmented-plane-wave wave functions changes the sharp structure found in the joint density of states, yields an L2,3 emission spectrum in good agreement with experiment, and indicates that band-structure effects play an important role in the observed x-ray threshold shape.
