Relativistic x-ray and Auger transition rates for variously ionized neon

Fully relativistic calculations on the energies and electric dipole rates of x-ray multiplets arising from states of 2p^q, 2s2p^q and 2s² 2p^q configurations of variously ionized neon with q ranging from 6 to 1 have been performed. The calculations have been carried out using multi-configuration Dirac–Fock wavefunctions with the inclusion of Breit interaction, quantum electrodynamics contributions and finite nuclear mass and size corrections. An attempt has been made to take into account the dominant contributions to correlation effects. Using a scaling procedure on the already available relativistic radial matrix elements for a single vacancy in the K shell, the Auger rates have been calculated. The numerical results for the x-ray and Auger transitions of double vacancy states of neon ionized to different degrees in the L shell have been compared with other available theoretical and experimental values. Due to the influence of both relativity and configuration interaction, the configuration average x-ray rates obtained from individual multiplet rates were seen to substantially differ from non-relativistic rates for many transitions.
