Abstract
A cross section set is reported for positron scattering from krypton and xenon over the energy range from zero to 1Â keV using the relativistic optical potential method. This set includes elastic, positronium formation, excitation, direct ionization, and grand total cross sections. They are compared to the recommended results of Ratnavelu et al. (J Phys Chem Ref Data 48:023102, 2019). The positronium formation cross section reported is represented by the sum obtained by successively lowering the ionization threshold to coincide with those for formation into the four lowest energy levels of positronium.
