High-resolution high-statistics Auger electron spectra were obtained in collisions of 20 MeV F[sup 6+] (1[ital s][sup 2]2[ital s]) projectiles with H[sub 2] targets using 0[degree] projectile electron spectroscopy. The 1[ital s]2[ital s]2[ital p][sup 2] [sup 3,1][ital D][r arrow]1[ital s][sup 2]2[ital s] ([ital D]---transitions) and the 1[ital s]2[ital s]2[ital p][sup 2] [sup 1][ital D][r arrow]1[ital s][sup 2]2[ital p] ([ital [bar D]]---transition) Auger transitions were clearly resolved. The 1[ital s]2[ital s]2[ital p][sup 2] [sup 3,1][ital D] projectile states can be formed by Resonance Transfer and Excitation (RTE),[sup 1,2] and thus their Auger decay to the 1[ital s][sup 2]2[ital s] state can interfere with [ital elastically] scattered target electrons giving rise to characteristic Fano-like line shapes. Their Auger decay to the 1[ital s][sup 2]2[ital p] state can interfere with [ital inelastically] scattered target electrons. Comparison with the results of existing RTEA-elastic electron scattering interference theory and asymmetry parameter are discussed. For the RTEA-inelastic electron scattering interference, calculations will soon be available.
