Spin polarization of Auger electrons from noble gases after photoionization with circularly polarized light

Spin polarization of Auger electrons arising from photoionization of atoms by circularly polarized light is studied theoretically. We present numerical calculations for the spin-polarization and angular anisotropy parameters of Auger decay for the Ar L 3 M 2,3 M 2,3 , Kr M 4,5 N 2,3 N 2,3 , Xe N 4,5 O 1 O 2,3 and Xe N 4,5 O 2,3 O 2,3 transitions. Our model employs Dirac-Fock wavefunctions using intermediate coupling for the final ionic states. We give complete data sets including relative intensities, angular distribution and all spin polarization parameters for the transitions considered, that are calculated consistently within one model.
