Using the multiconfiguration Hartree-Fock code by Cowan, Auger transition energies and radiative and nonradiative decay rates were calculated for doubly excited 3lnl′ and 4lnl′ (n≥4) states in Ne8+. The results are compared with previous theoretical results. The Auger yields for a given n are averaged over individual states. It is found that the average Auger yields for the configurations 3lnl′ (n=4–9) decrease slowly with increasing n while they are close to unity for the configurations 4lnl′ (n=4–7).
