In the impact velocity range of 0.2–0.6 a.u. we have measured line emission cross sections in the vuv and visible spectral region for collisions of C6+ with atomic hydrogen. The electron capture goes predominantly into then=4 shell and to a lesser extent into then=5 shell. For the dominant lines there is a good agreement with the molecular, the extended atomic and the unified atomic-molecular orbital calculations of respectively Green et al. , Fritsch and Lin , and Kimura and Lin . However for transitions originating from then=5 level the measurements strongly support the molecular orbital calculations. Furthermore there are considerable differences between measured and calculated intensities for the lines of non-dominantly populated high-n states (n=7 and 8) and atomic orbital and UDWA calculations.
