[en] Peculiar properties of ion-atom collision systems, in particular deviations from statistical populations of singlet and triplet levels, can be studied by optical spectroscopy.We have extended earlier studies by VUV spectroscopy of a number of collision systems at various collision energies in the 0.01-MeV/nucleon to 1-MeV/nucleon range, involving H+ 2 , H+, He+, He2+, Ne+, Ar+, and N+ 2 as projectiles and Ne, Ar, and N2 as target gases. Statistically signi cant deviations of the relative intensities of singlet and triplet lines from simple ratios are observed in the displaced terms of the valence shell of Ne III, corroborating and extending earlier work. For Ar III, the energy dependences of singlet-to-triplet excitation ratios are very
different for dff erent projectiles. For NII, in contrast, all observed line ratios are practically independent
of the projectile energy.
