High-resolution measurements of Ne K Auger electrons have been performed using multiply charged /sup 20/Ne projectiles in collisions with He, CH/sub 4/, and Ar at impact energies of 70 and 100 MeV. Kinematic line-broadening effects were substantially reduced by observing the electrons at 0/sup 0/ with respect to the beam axis. For the He-gas target the outer-shell electronic configuration of the incident ions is essentially retained during K-shell ionization. Thus, B-, Be-, and Li-like electron configurations were selectively produced for incident ions of Ne/sup 4 +/, Ne/sup 5 +/, and Ne/sup 6 +/, respectively. For target gases CH/sub 4/ and Ar, Li-like lines are found to be strongly excited, independent of the initial charge state of the projectiles.
