Ionization of He, Ne and Ar atoms by 1.05 MeV/amu Csup(q+) (q=2-6) and Arsup(q+) (q=4-14) ion impact

Total ''apparent'' ionization cross sections and partial cross section of the production of highly ionized recoil ions of He, Ne and Ar in 1,05 MeV/amu highly charged Csup(q+) (q=2-6) and Arsup(q+) (q=4,6,10-14) ion impact have been measured and compared with theoretical prediction and other experimental data. The total ionization cross sections have been found to scale as the square of the effective charge of projectile ions qsup(*), as predicted by theories. (orig.)
