Abstract

We report full quantum scattering cross sections for the peculiar 17 O + 17 O 17 O system, at relatively low collision energies. We consider different types of collision-induced transitions, as the indistinguishability of the three nuclei allows for the mixing of reactive, inelastic, and elastic processes. Furthermore, due to the nonzero nuclear spin of 17 O and the existence of nuclear spin isomers ortho-and para-O 2 , we pay particular attention to transitions between these two species, that is, the ortho-para conversion process. We find that the corresponding cross section has a magnitude comparable to that of the H + + H 2 counterpart.
