摘要：

From Mossbauer effect, lattice constant and susceptibility measurements we show that Eu is nearly divalent in Eu(Cu, Ag, Au)(P, As, Sb). However, the L(III) x-ray absorption spectra consist of a pronounced double structure, suggesting a non-integral mean Eu valence. The high-energy structure in the L(III)-edge spectra is interpreted as a final-state (shake-up) effect. This finding strongly supports the existence of final-state effects in the L(III) x-ray absorption spectra of divalent Eu compounds as previously reported by Sampathkumaran and co-workers in EuPd2P2.
