Repulsive potentials for the interaction of oxygen atoms with the noble gases and atmospheric molecules

Repulsive potentials between about 0.2 eV and 20 eV are determined for interactions of oxygen atoms with the noble gas atoms and with H 2, N 2, O 2, NO, CO, CO 2 and H 2O molecules from incomplete total scattering cross sections. Good agreement with theory is obtained for the noble gases. The potent...

Description
Summary:Repulsive potentials between about 0.2 eV and 20 eV are determined for interactions of oxygen atoms with the noble gas atoms and with H 2, N 2, O 2, NO, CO, CO 2 and H 2O molecules from incomplete total scattering cross sections. Good agreement with theory is obtained for the noble gases. The potentials for the interaction with molecules obtained by assuming spherically symmetric potentials are compared with the same potentials computed by averaging the cross sections for different orientations of the molecules. By introducing reduced variables, the problem of finding two isotropic potential parameters is simplified to a search for one, the other being determined by a least-squares constraint.
