Description
Context: Molecular oxygen is peculiar of Earth’s atmosphere and the precursor of stratospheric ozone which absorbs most of the Sun UV radiations. Oxygen isotopic analysis allows one to trace back the origin of elements constituting Solar system primitive materials, like meteorites and comets. O
Methodology: We have used a high quality ab initio potential energy surface [5] to perform computationally intensive full quantum investigation of the dynamics of this scattering process.
Results: We shall present cross sections and rate constants [6,7,8] for the
