Nr. Singh et al., POSITRONIUM FORMATION CROSS-SECTIONS FOR SCATTERING OF POSITRONS FROMPOTASSIUM AND RUBIDIUM, Australian journal of physics, 47(3), 1994, pp. 265-270
Total cross sections for positronium formation in positron-potassium a
nd positron-rubidium scattering have been calculated in a distorted wa
ve approximation for incident positrons in the energy range 1 to 50 eV
. The present results are compared with other theoretical results and
with measurement where available.
