Energy spectra of electrons produced in collisions of multiply charged neon ions with noble-gas atoms

Energy spectra of electrons produced in collisions of 100 keV Ne n+ (n=1, 2, 3, 4) on He, Ne, Ar and Kr have been measured. The experimental data show that capture of two electrons into excited autoionising states of the projectile is important for the Ar and Kr targets. For the Ne and He targets capture of two electrons into excited states is less probable.
