The relativistic distorted-wave method was used to perform calculations
for electron impact excitation of the first (n
levels of Na, K
and Rb at incident electron energies in the range 20–200 eV.
Scattering parameters presented include differential and integrated
cross sections, differential and integrated Stokes parameters,
generalized STU-parameters and various collisional alignment and
orientation parameters.
Comparisons with experiment and other theories are in agreement except
for cases where first-order methods have been previously proven to be
insufficient.
Relativistic effects, mainly due to the spin-orbit interaction, have
been found to be prominent for rubidium.
