Abstract

The inelastic scattering of positrons by 11 lithium-isoelectronic ions, (with nuclear charges Z=4,5,... 14) is investigated for the first time within the framework of the coupled-static and frozen-core approximations. It is assumed that the elastic and positronium channels, in each process, are open and all excitation channels of the target are closed. The calculations of the total cross-sections are carried out by employing eight partial waves, (corresponding to 0≤l≤7, where l is the total angular momentum of the scattering problem considered). Also, the effect of switching on the polarization potentials of the positroniums on the rearrangement cross-sections is investigated in details. Particular attention is devoted to the relation between the positronium formation cross-sections and the increase in the nuclear charge of the targets.
