In this work we have made an intense theoretical effort to determine accurate {ital K}-Auger transition energies, Auger rates, and line intensity ratios for Be- and B-like multiply charged neon ions using several different atomic models. Theoretical data on Li-like states in Ne VIII are also reported. In particular a detailed study of Auger line intensity ratios is presented. For several Be- and B-like states strong cancellations in the Auger matrix elements are predicted. These rates are quite sensitive to the atomic wave functions. We have also deduced experimental Auger intensity ratios for Be and B-like Ne ions from previous data. In order to classify our high-resolution projectile spectra, theoretical Auger energies and rates for various terms of the electron configurations 1{ital s}2{ital s}{sup 2}2{ital p}{sup {ital n}{minus}1}, 1{ital s}2{ital p}{sup {ital n}+1}, and 1{ital s}2{ital s}2{ital p}{sup {ital n}} ({ital n}=1--3) have been calculated relativistically, using the saddle-point technique, the multiconfiguration Dirac-Fock model, and the 1/{ital Z} expansion method. Several previously unknown line identifications of Be-like states in Ne VII and B-like states in Ne VI are reported.
