Abstract

The multiconfiguration Hartree-Fock method has been applied to study low-energy scattering of electrons from argon atoms. The polarization of the argon atoms due to the scattered electron and the electron-correlation effects that are very important in the calculation are taken into account in the ab initio way more accurately through the configuration-interaction procedure. Phase shifts for various partial waves calculated in this approximation have been used to calculate elastic differential, total elastic, and momentum-transfer cross sections. The present results are compared with the experimental and other theoretical results. It is found that the present results are in very good agreement with the experimental results and compare well with the other theoretical results.
