Auger-electron spectra produced in the collision of 80-MeV Ar{sup 5+}+He were measured with high resolution. The spectra are dominated by the Auger decay of the Ar{sup 6+} projectile in a configuration with a hole in the 2{ital p} shell. All of the observed transitions can be identified by means of multiconfiguration calculations for transition energies. The line intensities are compared with transition rate calculations using the intermediate-coupling scheme. The observation of an Auger transition, which is forbidden in the single-configuration picture, is interpreted as being due to electron-correlation effects.
