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 state-resolved differential cross sections have been determined with respect to the main quantum number, subshell level and spin state of the captured electron
