摘要：

Using an alternative technique to trap keV ion beams, the kinetic-energy release after dissociative charge transfer of vibrationally cold HeH+ was measured. The results indicate that rapid radiative vibrational cooling takes place during the trapping, thus allowing a direct observation of the a (3)Sigma(+) metastable state of HeH+, which has been a subject of controversy in previous dissociative recombination experiments.
