Abstract

We present calculations of the $3^{2}$ S and $3^{2}$ P spin asymmetries and $L_{⊥}$ for singlet and triplet scattering for projectile energies of 10 and 20 eV. Together these observables give a most stringent test of any electron-atom scattering theory. We find excellent agreement between the results of our coupled-channel optical method and experiment, which for the spin asymmetries can only be obtained by a good description of the couplings between the lower-lying target states and the target continuum.
