Abstract
Elastic amplitudes for -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 -H cross section, and assuming unitarity, the total -H scattering cross section.
