Abstract
Cross sections for positron-rubidium scattering have been calculated in a five-state close-coupling approximation, with polarized frozen-core Hartree-Fock wavefunctions, for energies in the range 3.7-48.1 eV. In addition, the low-energy elastic scattering cross sections have been determined by a polarized-orbital method. These latter results exhibit a large shape resonance at very low energy. Comparison of the theoretical results is made with recent experimental measurements.Keywords
