Abstract

In this work, we present theoretical fully differential cross sections (FDCS) for the single ionization of argon by positron impact obtained by means of the CDW-EIS model. the impact energies considered are 113.5 eV and 200 eV. the obtained angular distributions for 2eV and 5 eV emitted electrons are compared to those obtained for electron impact under the same energetic configuration. in particular, we show that the shape of the binary structure evolves from a single peak to a two-peak structure as the projectile scattering angle is increased. Similar conclusions apply for the usually termed recoil peak structure.
