A calculation for the scattering of low-energy positrons by Helium atoms

  • Published:
Zeitschrift für Physik

Abstract

A variational calculation has been performed for the elastic e+-He scattering at energies below 16 eV. Partial waves up toL=3 are included. The trial functions contain distortions which take into account virtual positronium formation. The results of the calculation show good agreement with experimental cross section data.
