    Abstract

    State-selective capture and emission cross sections for single-electron capture in collisions of bare C6+ ions and He-like O6+ ions with helium are presented for impact velocities between 0.05 and 0.27 au (62 = E (eV amu-t)) = 1852). Experimental data have been obtained using VUV photon emission spectroscopy. They join previous higher energy measurements smoothly. Detailed comparisons are made with existing AO and MO close-coupling calculations. The entire data set is consistent with results concerning the influence of the projectile core on the capture process found in a theoretical study on collisions between multiply-charged ions and atomic hydrogen.
