2021

Abstract We report the rotational-state resolved integral cross sections and differential cross sections for 18O + 16O16O (v = 0, j = 1) → 18O16O ( v ′  = 0, j ′ ) + 16O and 16O + 18O18O (v = 0, j = 1) → 18O16O ( v ′  = 0, j ′ ) + 18O reactions obtained using time-independent quantum mechanical method on an ab initio potential energy surface of ozone [Dawes et al. J. Chem. Phys.135, 081102(2011)]. The results for both the reactions in the collision energy range of 0.001 – 0.1 eV are presented and discussed the isotopic effects found. The present results are compared with the earlier experimental and theoretical results reported in the literature.
