Collisions between 98-keV N7+ ions and a HCl target have been investigated experimentally. The kinetic-energy distribution of fragment H+ ions originating from multiple electron capture was detected at angles in the range 20°-160° with respect to the incident beam direction. Proton energies as large as 100 eV were observed, and calculations made in the simple Coulomb explosion model suggest that up to seven target electrons may be involved during the collision. Using the Landau-Zener model, we show that the N7+ projectile mainly captures outer-shell electrons from HCl. From the experimental data we derived multiple-capture cross sections which we compared with results from a model calculation made using the classical over-barrier model and also with a semiempirical scaling law. For the specific case of double capture, several structures appeared, which were assigned using ab initio calculations to states of HCl2+. © 2005 The American Physical Society.
