Phys. Rev. Lett. 56, 2744–2747 (1986)Towards a Self-Consistent Determination of the Mixing Parameters in the Anderson Model: An Application to the 4f-Excitation Spectra of YbPReceived 20 December 1985; published in the issue dated 23 June 1986 A method is presented for computing the mixing parameters in the Anderson model for heavyrare-earth compounds, based on a linear combination of atomic orbitals fit to a self-consistent band-structure calculation. An appropriate average of these parameters is used in a many-body calculation of the valence-band x-ray-photoemission and inverse-photoemission spectra of YbP, with the Coulomb integral U as the only adjustable quantity. The calculated inverse-photoemission spectrum agrees qualitatively with room-temperature low-resolution data by Baer et al. © 1986 The American Physical Society URL:
