Abstract: | Summary The total elastic cross-sections of the collisions of positrons with various hydrogenlike targets (with nuclear chargeZ=1, 2, 3, 4, 5 and 11) are determined at 13 values of the incident energy lying below 6.8 e V(the positronium formation threshold
of e+-H scattering). The inelastic scattering of positrons by the same targets is investigated for the first time at energies above
the positronium formation thresholds. Both scattering processes are treated using a coupled-static formalism and an iterative
Green's function partial wave expansion technique. The resulting cross-sections demonstrate the stability of this technique
and emphasize the importance of exploring the aspects of positron-ion collisions more fundamentally on both theoretical and
experimental levels. |
