Multiple ionization of neon 2s- and 2p-electrons induced by ion atom collisions

Absolute cross sections for production of the 1s22s2p5 and 1s22s02p6 configurations of neon in collisions of H+, He+ and Ne+ with Ne and He have been measured by observation of radiative transitions in the spectral range of the vacuum ultraviolet for energies between 50 keV and 1 MeV. Projectile and target emission have been separated. The dependence of the cross sections upon impact velocity is discussed and compared with theoretical calculations. The relative population of the 1P1 and 3P2, 1, 0 and the 3P2, 1, 0 fine structure levels of the 1s22s2p5 configuration is measured as function of impact velocity for the different projectile target combinations.
