Excitation of the np(5)(n plus l)p (J=1,2 and 3) states of the inert gasesby spin-polarized electrons: integrated state multipoles and Stokes parameters

Relativistic distorted-wave calculations are carried out for the excitation of all the np(5)(n + 1)p J = 1, 2 and 3 states of neon (n = 2), argon (n = 3), krypton (n = 4) and xenon (n = 5) from the ground np(6) J = 0 state by spin-polarized electrons. Results are reported for the integrated state mu ltipoles of the different excited states for incident electron energies up to 300 eV. Using the integrated state multipoles for the excited states of neon and krypton, the integrated Stokes parameters are evaluated and compar ed with recent experimental measurements.
