Study of the interactions of atomic and molecular oxygen with O2and N2by scattering data

摘要

Absolute total scattering cross sections for the O2ndash;O2, O2ndash;N2, Ondash;N2, and Ondash;O2systems are measured in the thermal energy range. A glory structure is present for O2ndash;O2, O2ndash;N2, and Ondash;N2. For Ondash;N2this structure appears to be partially quenched due to the anisotropy of the3Poxygen atom. For Ondash;O2the structure is almost completely quenched because of the presence of a manifold of interactions. From the analysis of the cross section data, information about the interaction potential of all these systems of atmospheric interest is obtained. For O2ndash;O2a potential able to reproduce also the spectroscopic and thermophysical data is proposed.
