Radiative Auger spectra of several K and Ca compounds

K-MM radiative Auger (RA) spectra have been measured for several compounds containing K and Ca. Transition energies are evaluated by the use of various sources: the DV-X_α calculation, term values from optical spectroscopy, and L-MM Auger energies. It is shown that the DV-X_α calculation is very useful in the understanding of RA spectra; calculated transition energies agree well with observed ones as well as those estimated from optical data, giving an unambiguous assignment for the observed spectra. On the other hand, transition energies evaluated from L-MM Auger energies sometimes disagree with others. Possible reasons for the discrepancy are discussed.
