We have measured the cusp electron yield in coincidence with the transmitted charge state (He0, He+ and He++) when3He+ collides with He and Ne under single collision conditions. For the first time this enables the electron capture to the continuum (ECC) yield to be directly compared with that from electron loss to continuum (ELC). While the ECC contribution is smaller than that from ELC at high projectile velocities (Vp >3 au) the data suggest that ECC will dominate below Vp=2.8 au. The relevance of the results to the projectile velocity dependence of existing capture theories is discussed.
