Title: 25-state calculation for e(-)-Na-2 scattering
Author: Natalense, APP

Abstract: We use the Schwinger multichannel method with pseudopotentials to study low energy e(-)-Na-2 scattering. Our cross sections, for impact energies from 0 to 10 eV, include polarization effects and up to 25 open channels related to all electronic states lying below 3.5 eV. Our results predict prominent threshold effects due to a very intense coupling between the B(1)Pi(u) state and the elastic channel in an energy region where there is no experimental data. Our total 25-state cross sections are in very good agreement with available experimental data for energies below about 4 eV. [S0031-9007(98)07561-9].
