THE ELASTIC SCATTERING OF LOW ENERGY ELECTRONS FROM ATOMIC HELIUM.

Abstract

Elastic electron scattering from atomic helium is examined within the framework of perturbed HartreeFock theory for the energy region from 0 to 50 eV. Interaction potentials are derived to describe the distortion induced into the target atom by the incident electron in the adiabatic approximation. Dynamical corrections to the adiabatic approximation are also examined and these incorporated into the formalism through a 'velocitydependent' potential. The s-, p-, and d-wave scattering phase shifts were computed by numerical iteration of the resulting equations. These phase shifts are then used to compute the elastic scattering cross sections and the results compared with other recent theoretical predictions and experimental data. (Author)
