Scattering of Bloch electrons in Pd(H) beyond the average t-matrix approximation

Abstract

De Haas-van Alphen scattering quantities are calculated for the dilute interstitial alloy Pd(H). In the KKR Green function formulation the authors used all multiple scattering effects associated with host embedment; lattice distortion and charge transfer are accounted for exactly within the muffin-tin approximation. In contrast to ATA calculations made previously, the present results agree very well with experiment. Also, attention is paid to the measured isotope effect.
