In this work we report an improved experimental determination of {ital K}-shell binding energies from Be-like Ne{sup 6+}, B-like Ne{sup 5+}, and C-like Ne{sup 4+} ground-state multiply charged ions using high- resolution Ne-K Auger-electron spectroscopy. The derived energy differences, namely, Ne{sup 6+} E(1{ital s}{sup 2}2{ital s}{sup 2}) {sup 1}{ital S}--Ne{sup 7+} E(1{ital s}2{ital s}{sup 2}){sup 2}{ital S}, Ne{sup 5+} E(1{ital s}{sup 2}2{ital s}{sup 2}2{ital p}) {sup 2}{ital P}{degree}--Ne{sup 6+} E(1{ital s}2{ital s}{sup 2}2{ital p}) {sup 3}{ital P}{degree}, and Ne{sup 4+} E(1{ital s}{sup 2}2{ital s}{sup 2}2{ital p}{sup 2}) {sup 3}{ital P}--Ne{sup 5+} E(1{ital s}2{ital s}{sup 2}2{ital p}{sup 2}({sup 3}{ital P})) {sup 4}{ital P} are 1099.1, 1048.5, and 1001.8 eV, respectively. These energies are accurate to within {plus minus}0.1 eV. Theoretically, we have studied relativistic binding energies of Ne{sup {ital q}+} ({ital q}=6, 5, and 4) by using the (i) saddle-point technique, (ii) 1/{ital Z} method, and (iii) multiconfiguration Dirac-Fock model. Excellent agreement with experiment is obtained.
