Résumé

We report full quantum integral and differential cross sections and rate constants for the O-17 + O-32(2) reactive process. This constitutes the first quantum scattering study of the (OOO)-O-17-O-16-O-16 system. We emphasize the comparison with the O-18 + O-32(2) collision in close connection to the mass-independent fractionation (hereafter referred to as MIF) puzzle for ozone in atmospheric chemistry. We find similar general trends in the cross sections and rate constants for both rare isotopes, but we note some singular behaviors peculiar to the use of O-17 isotope, particularly at the lowest collision energies.
