Moment $T$ -matrix approach to $e^{+}$ -H scattering. II. Elastic scattering and total cross section at intermediate energies

Abstract

Elastic amplitudes for $e^{+}$ -H scattering are calculated for positron energies from 0.25-1.15 a.u. (∼7-34 eV), an energy range where pickup and impact-ionization channels are open. These amplitudes are used to calculate the elastic $e^{+}$ -H cross section, and assuming unitarity, the total $e^{+}$ -H scattering cross section.
