Abstract [en]

We have studied the multielectron processes in close collisions between slow Neq+ ions (q=1-9, energies of 5 and 14 keV) and Ar atoms through measurements of the charge-state correlations between 27 degrees scattered and 70 degrees recoiling ions. At the selected scattering angle, the internuclear distance of the closest approach at 35 keV is comparable to the L-shell radius of Ar atoms. A drastic difference between low-charged (q=1-3) and highly charged (q=7-9) Ne ions was found. For example, the most probable channel for the Ne7+ projectile is three-electron capture accompanied with two-electron loss whereas for the Ne+ projectile pure double ionization was found most probable. As a general trend, the mean charges of the both ions and the mean number of captured electrons increase almost linearly with incident charge q, while the mean number of ejected electrons from the system is independent of q at both 5 and 14 keV. We also measured the charge state distributions of the Ar recoil ions as function of the Neq+ (q=3, 5, and 7) energies between 5 and 63 keV, which corresponds to distances of closest approach between 0.6 a.u. and 0.17 a.u. We found that the charge of the Ar ions increases at internuclear distances less than 0.32 a.u.
