摘要：

We perform convergent close-coupling (CCC) calculations of electrons scattering on atomic sodium. We show that the results are in excellent quantitative agreement with the measurements of spin asymmetries and singlet and triplet L(perpendicular to) at the two projectile energies considered of 10 and 20 eV. The CCC method is the only one that is able to achieve this to date, and demonstrates that the very large effects of the target continuum are very accurately treated using square-integrable states. The method is applicable to all hydrogenlike atoms or ions and all projectile energies.
