Scattering of High-Velocity Neutral Particles Xvii. Ar-O2, Ar-N2, Ar-Co

摘要

Fast Ar beams with energies between about 200 to 1500 eV have been scattered by room temperature O2, N2, and CO to obtain the reaction potentials. The peripheral-force approximation, which assumes that the centers of force in a molecule are located at the nuclei of each atom, has been used to construct the individual atom-atom interactions which combine to make up the experimental atom-molecule potentials. Potentials have also been derived for the following atom-molecule and molecule-molecule systems by continuing the peripheral-force approximation with established semi-empirical combination rules. With the exception of molecule-molecule systems involving NO there is good agreement between the derived potentials and those obtained directly from scattering experiments. (Author)
