{ital L} Auger-electron emission from Na-like configurations populated in iron projectile ions have been measured with high-energy resolution. The Auger states have been formed in collisions of 170-keV Fe{sup 17+} ions with He and Ne target atoms. The dominant spectral structures are due to Auger decay of states with the configurations 1{ital s}{sup 2}2s{sup 2}2p{sup 5}nln{prime}l{prime} in Fe{sup 15+} and in particular from the 1{ital s}{sup 2}2s{sup 2}2p{sup 5}3s3p {sup 4}D{sub 7/2} metastable state. The absolute energy of the 3{ital s}3{ital p} {sup 4}{ital D}{sub 7/2} level is measured, and its metastable nature is demonstrated. Line assignments are obtained by using calculated transition energies and rates and by comparison to previously measured optical spectra.
