Using the multiconfiguration Hartree-Fock code by Cowan, Auger transition energies and radiative and nonradiative decay rates were calculated for doubly excited 3${\mathit{lnl}}^{\prime }$ and 4${\mathit{lnl}}^{\prime }$ (n≥4) states in ${\mathrm{Ne}}^{8+}$. 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 3${\mathit{lnl}}^{\prime }$ (n=4–9) decrease slowly with increasing n while they are close to unity for the configurations 4${\mathit{lnl}}^{\prime }$ (n=4–7). © 1996 The American Physical Society.
