Abstract The core - corrected Glauber approximation (CCGA)is employed for the first time for treating elastic and inelastic collisions of positrons with positive ions. particularly, the e+ - Be + and e+ - Mg + scattering processess are considered. A model potential technique based on the one - valence - electron model of the target is used with Clementi - Roetti`s wavefunctions and ground -state energies. Wavefunctions of the np excited states are considered as partial derivatives of the corresponding ground-state wavefunctions. To guarantee consistency the binding energy of the valence -electron of the corresponding states. Differential and total elastic and excitation (from ns to np states) cross sections are calculated in an energy region from 10 to 100 eV. The resulting cross sections are compared with those determined bt other authors(e.g this results agree with those obtained by Gien (1987b)), and Gien and Yan(1990). |
