Charge Transfer Model for Quadrupole Interactions and Binding Energies of Point Defects with111In/Cd Probes in Cubic Metals

摘要: A simple model is used to predict nuclear quadrupole interactions caused by point defects at near-neighbor sites of probe atoms in cubic, metallic hosts. Also predicted are binding energies between the and impurity atoms. The assumes that electrostatic predominate over strain interactions. It critically examined using data for111In/Cd probes next solute noble metal hosts, obtained mostly K. Krolas, vacancies metals intermetallic phases. magnitude found correlate well with charge transfer host defect. Charge taken be proportional difference work functions defect elements.
