Abstract

Single electron capture in collisions of 9 keV/q Ne7+ -ions with He has been studied using cold-target recoil-ion momentum spectroscopy (COLTRIMS). With an improved apparatus a longitudinal momentum resolution of 0.07 a.u. has been achieved. This momentum component corresponds to the binding energy of the active electron in the final state. For the first time stateresolved differential cross sections have been determined with respect to the main quantum number, subshell level and spin state of the captured electron.
