Angular Correlation Studies of Electric Field Gradients in Dilute Silver Alloys

Abstract
Measurements of the angular correlation of cascade gamma rays have been used to investigate electric field gradients at lattice sites in dilute silver alloys. The field gradients arise from the redistribution of conduction electrons around solute atoms (valence effect) and from the distortion of the host lattice by these atoms (size effect). The results indicate that the valence effect is predominant but that the size effect can be comparable in magnitude in some cases.
