Atom--diatomic molecule kinetic theory cross sections

Classical expressions for the generalized or kinetic theory cross sections for gases of diatomic molecules derived earlier are specialized to describe atom--diatomic molecules collisions and developed further. Numerical results based on parameters intended to describe Ar--N2 collisions are then presented and the resulting generalized cross sections are compared with those derived from experimental studies of the Senftleben--Beenakker effect on the viscosity of mixtures of argon and nitrogen. The results indicate that the experimental values may be reproduced using reasonable values of the anisotropy parameters
