Electron impact excitation of the np5nd and np5(n + 2)s states of Ar (n = 3) and Xe (n = 5) atoms

Electron impact excitation of all the np5nd, J = 0, 1, 2, 3 and 4, and np5(n + 2)s, J = 0, 1 and 2 states of argon (n = 3) and xenon (n = 5) atoms from the ground np6 J = 0 state has been considered in the fully relativistic distorted-wave approximation theory. Results for the differential cross sections are calculated in the incident electron energy range of 15 to 100 eV. The results at selected energies are only presented. These are compared with the available experimental data and where possible with the only available non-relativistic unitarized first order many body theory calculations. (author)
