Abstract
Absolute cross sections for the formation of positronium in positron collisions with He, Ar, and have been measured for incident positron energies up to 76.3 eV. The results are markedly different, in magnitude and energy dependence, from those of Charlton et al. The measurements in He and agree well with distorted-wave and charge-exchange calculations.
