Absolute Extreme Ultraviolet emission cross-sections have been measured for collisions between C5+ and H2O in the range of 0.113 to 3.75 keV/amu (170-979 km/s). These results are used to derive velocity-dependent triplet-to-singlet ratios and emission cross-sections of the Cv K-series following single-electron capture. Comparison with existing measurements of integral charge-changing cross-sections indicates that auto-ionizing multi-electron capture is a significant reactions channel. This reaction may indirectly populate the n=2 states and thus add strength to the K alpha emission of Cv ions thereby co-determining the hardness ratio of K-series emission of Cv.
