Abstract

Electronic stopping powers for fixed-charge-state He ions, He2+ and He+ , in Al target are calculated within the framework of linear-response dielectric theory by using the dynamic local-field correction in the dielectric function and the concept of local plasma density approximation. An average stopping power has been defined by weighting the fixed-charge-state results with theoretical occupation probabilities. Satisfactory agreement between this average stopping power and experimental data, measured for He-ion beam, is found.
