摘要
The elastic scattering of positrons from the heaviest noble gases has been formulated by using a parameter-free semiclassical model for the polarization forces in the short- and intermediate-range distances. The exact Coulomb repulsive interaction has been obtained from self-consistent-field wave functions of near-Hartree-Fock quality and the scattering equations have been solved over a broad range of collision energies. The elastic integral cross sections agree well with experiments in spite of the great simplicity of the employed computational model. Angular distributions also compare favorably with available experiments and the relative importance of various second-order corrections is discussed in relation to their bearing on the final results. © 1994 The American Physical Society.
