Local potentials equivalent to matrix effective potentials for e-He scattering at 200 and 400 eV

Abstract

We have obtained equivalent local potentials (ELP's) to matrix effective potentials for e-He scattering at 200 and 400 eV by means of semiclassical WKB inversion of the phase shifts. The absorptive parts of these ELP's are compared with current models for absorption potentials. © 1984 The American Physical Society.
