Abstract
The K betaIII,IV, and K betaVII,VIIIX-ray satellite groups have been measured with high resolution in Na, Mg and Al metals as well as in Na2O. The spectra interpreted in terms of KLnto LnV(n=1, 2) transitions, are analysed in detail using experimental initial multiplet energies from the KLnto Ln+1X-ray transitions. The final-state energies are taken from optical spectra presuming fully screened Lncore holes. The results show this assumption to be justified. The K betaVII,VIIIband is here reported for the first time for Na, and also in Mg and Al it has a peak not found earlier. In metals these spectra allow new testing possibilities for the final-state rule. In Na2O the K betaIII,IVband is a clear duplet of K beta0cross transitions but the K betaVII,VIIIband spreads out to a diffuse hump due to interaction between the sodium L2holes and the localised oxygen valence orbitals. The K2Lnto KLn+1(n=0, 1)hypersatellite spectra overlapping with the K betaVII,VIIIbands in aluminium were separated from the latter and the energies of the multiplet transitions were determined and found to agree with theoretical energies calculated using the multiconfiguration Dirac-Fock method.
