Calculation of electron scattering on silver

The relativistic convergent close-coupling (RCCC) method has been applied to study electron scattering from silver and obtain differential and integrated cross sections for elastic scattering and excitation to the $4d^{10}5p$, $4d^{10}6s$, $4d^{10}6p$, $4d^{10}5d$, $4d^{10}7s$, and combined $4d^{10}7p$, $4d^{10}6d$, and $4d^{10}4f$ states for incident electron energies up to 500 eV. In addition to the cross sections we have obtained Stokes parameters for the $(4d^{10}5p)^2P_{3/2}$ state and elastic spin asymmetries. The silver atom is described by a model of a single electron above a frozen [Kr]$4d^{10}$ core. Empirical one- and two-electron polarization potentials have been used to obtain the best representation of the target state energies and the optical oscillator strengths. To test convergence we have conducted calculations using a number of models and present results for two target states models, one consisting of 22 bound states and 28 continuum states, and the other extending the number of continuum states to 58. Good agreement was found with available experimental data for elastic scattering and $4d^{10}5p$ excitation differential cross sections.
