摘要：

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.
