The translational energy spectroscopy technique has been used to study single-electron capture processes for collisions of slow Ne(q+) ions (q = 3-6, where q is the projectile charge state), produced in a recoil ion source, with He, Ne and Ar at laboratory impact energies between 100 and 600 eV and scattering angles between 0-degree and 6-degrees. The measurements show that the dominant reaction channels are due to capture into excited states of the projectile products and show a dependence on scattering angle. There is clear evidence of the presence of the first and second metastable states in the incident Ne3+ ion beam. A reasonable description of the dominant final states is obtained in terms of the reaction windows, which are calculated using the single-crossing Landau-Zener model. The measured differential cross sections show that the projectile products are distributed with maximum intensity near a scattering angle theta(c) which corresponds to capture at an impact parameter equal to the crossing radius.
