Abstract

We have observed the production of [Formula Presented] ions by the bombardment of gaseous mixtures of [Formula Presented] and He with slow positrons and measured its dependence on the positron energy. The formation is believed to involve vibrational excitation of [Formula Presented] via positronium formation, followed by proton transfer from [Formula Presented] to He. The significance of these results with respect to astrophysics is discussed.
