Description

Coupled-state calculations in a K(4s, 4p, 5s, 5p, 3d) + Ps(1s, 2s, 2p, 3s, 3p, 3d) approximation are reported for positron scattering by ground-state potassium in the energy range 0.5-60.0 eV. Comparison is made with the earlier work of Hewitt et al (1993, 1994) in a K(4s, 4p, 5s, 5p) + Ps(1s, 2s, 2p) approximation. For the first time cross sections for positronium formation in n = 3 states are obtained. (author)
