Observation of KL2,3L2,32V satellite Auger transitions in Mg metal

A satellite structure to high energy of the K-L 2,3 V band spectrum in metallic Mg has been resolved using soft X-ray excitation. The observed energy of the structure is shown to be consistent with that predicted for KL 2,3 -L 2,3 2 V transitions on the basis of excited atom Delta SCF Hartree-Fock calculations. The spectral profile is shown to be adequately reproduced using the K-L 2,3 V lineshape and the multiplet structure of the initial and final states.
