Abstract

Bloch electron scattering quantities (Dingle temperatures and cross-sectional area changes) are calculated for the light interstitial impurities H, B and C in palladium. A KKR-Green-function method for dilute interstitial alloys is used. All multiple-scattering effects are accounted for exactly within the muffin-tin approximation. It is found that the scattering quantities depend strongly on embedment effects such as charge transfer and lattice distortion. A comparison with experimental data obtained by de Haas-van Alphen spectroscopy is made. The calculated values for Pd(H) and Pd(C) are in good agreement with the experimental values. The results for Pd(B) are less good.
