Abstract

Total cross sections for positron-impact ionization are calculated in a relativistic formulation for the hydrogen atom for incident positron energies up to 10 times the ionization energy. Different sets of distorting potentials are used to study the mutual screenings of the outgoing positron and electron. A large discrepancy is noted between available theoretical and experimental data.
