Abstract

The interaction of electrons and atomic sodium was studied by using the momentum space coupled-channel optical method at low-impact energies. Total scattering cross sections have been calculated, and negative-ion resonances have been located. The present calculation results are in good agreement with available experimental data and previous theoretical results. We have obtained resonance features at $4.166$ and $4.502$ eV and also found possible resonance structures near the ionization threshold in the total cross sections.
