摘要：

Experimental studies of electrons ejected in ionizing collisions between C+, C2+, and C3+ projectiles and He and Ne targets have been made for incident projectile energies of 83, 100, and 150 keV/u. The data exhibit pronounced maxima in the 10-degrees ejected-electron energy spectra and projectile-charge-dependent shifts of these maxima which strongly supports the hypothesis of an independent ''saddle-point'' ionization mechanism. A possible cause of disagreement between these results and existing experimental data is also discussed.
