Probing electronic states of Ne-2(+) and Ar-2(+) by measuring kinetic-energy-release distributions
Dissociative decay of metastable, electronically excited neon and argon dimer ions produces fragment ions with strikingly dissimilar kinetic-energy-release distributions. The distributions have been modeled based on ab initio calculations of potential energy curves. The unusual bimodal distribution observed for dissociation of Ne-2 (+) arises from competition between radiative and nonradiative decay of the long-lived II(1/2)(u) state. For Ar-2 (+), however, electronic predissociation is insignificant.
