Abstract
We present results of electron-sodium scattering for the 3D→3P transition at the projectile energy of 5 eV calculated using the convergent close-coupling method. These include spin-resolved and spin-averaged alignment, orientation, and coherence parameters, as well as differential cross section and spin asymmetry. This calculation simultaneously produces results for the transitions 3P→3P at 6.52 eV and 3S→3P at 8.62 eV, which are also presented. The three transitions are used to study the nature of the convergence in the close-coupling expansion. We find our results to be in excellent agreement with experiment, where available.
