β¦ Synopsis
In order to allow for the relative increase of self-interaction in few-electron systems, a reduction factor is introduced into the statistical freeelectron exchange potential. This netexchange potential has been used in the calculation of elastic electron scattering by rare-gas atoms in the lo~-energy region from 0 to 10 eV. U'hereas former sttempts to treat thew phenomena as simple potential scattering have failed, in this work at least a crude qualitative ageement with experimental data has been achieved in most uses.
