Description
Summary:We present spin-asymmetry parameters (Sherman functions) for elastic electron scattering on zinc and mercury atoms calculated using the relativistic convergent close-coupling method for quasi-two-electron atoms above an inert core. The results for mercury are in excellent agreement with experiment across a wide range of energies. Similarly for zinc, we find excellent agreement between theory and experiment for energies below 9.0 eV. However, at 11.0 eV there is a discrepancy between theory and experiment, most likely due to a resonance excitation of a core electron.
