Phys. Rev. B 41, 12509–12513 (1990)Linear-response theory for core-hole screening in transition metalsReceived 12 March 1990; published in the issue dated 15 June 1990 An inverse dielectric matrix obtained in a mixed-band-structure scheme has been used in expressions for the core-hole-induced charge density n(r) and screening energy Rm. In this scheme n(r) and Rm are separable into isotropic and anisotropic contributions. Numerical results of n(r) and Rm have been predicted for a number of transition metals. The calculated and excited-atom-model results for Rm agree to within 5% for all the metals. The d-electron contribution to the screening energy is found to be of the order of 20–40 %. © 1990 The American Physical Society URL:
