The effect of the core hole on X-ray emission spectra in simple metals

• Shows that one-particle calculations of X-ray spectra with and without the core hole can give drastically different results, indicating a breakdown of one-particle theory. Only emission spectra obtained in the absence of the core hole consistently show a close resemblance to experiment. The authors show, that this fact can be explained by the many-body theory of Nozieres and DeDominicis (1969). They are then able to give the first interpretation of the L2,3 satellite spectrum of sodium.(17 refs)
