Title: Continuum Effects for Positron Scattering from Sodium Authors: Kuru Ratnavelu and N. Natchimuthu Affliations: Institute of Mathematical Sciences University of Malaya 50603 Kuala Lumpur, MALAYSIA Summary: Positron scattering from atomic sodium is studied at energies from 3 to 50 eV using the close-coupling approach that has allowed for the psoitronium effects aswellas the continuum effects. The continuum effects has been incorporated using the optical potential method.
