Symmetry Effects in Gas Kinetics II: Ortho- and Para-hydrogen

Abstract

The Manchester University Mk I computer has been used to calculate accurately the viscosity cross section for hydrogen molecules, and its dependence on the symmetry of the wave function for binary collisions. The calculations assume a central intermolecular potential of (exp, 6, 8) type, and cover reduced temperatures in the range 0.05 ⩽ T* ⩽ 2.0.
