Phys. Rev. B 58, 3741–3749 (1998)X-ray absorption and resonant inelastic x-ray scattering in the rare earthsReceived 25 February 1997; revised 10 March 1998; published in the issue dated 15 August 1998 This paper makes a comparison between x-ray absorption (XAS) and resonant inelastic x-ray scattering (RIXS) in the rare earths. Atomic calculations are given for 2p⃗4f. The radiative decay of the XAS final states is described for the situations where the core hole created in the absorption process is filled by a valence electron or by an electron from a shallower core level. RIXS spectra 4fn→3d¯4fn+1→4fn integrated over the outgoing photon energy (fluorescence yield) are compared with 3d⃗4f XAS. Sum rules related to XAS and RIXS and their applicability are discussed. © 1998 The American Physical Society URL:
