We report angle-resolved studies of projectile [ital L][sub 2,3]-shell autoionization electron emission by bombarding a polycrystalline Al surface with 0.2--5-keV Ne[sup +] ions. Several previously unresolved transition lines have been observed and assignment to Ne 2[ital p][sup 3][ital nln][prime][ital l][prime][ital n][prime][prime][ital l][prime][prime] and Ne[sup +] 2[ital p][sup 3][ital nln][prime][ital l][prime] autoionizing states has been proposed. We found that the [sup 3][ital P] triplet is the dominant configuration for the excited Ne 2[ital p][sup 4]3[ital s][sup 2] and its relative population depends sensitively on both the primary ion energy and incidence angle. Analysis of the electron spectra shows that most excited Ne particles are backscattered from the surface and decay in vacuum, rather than inside the solid.
