Quantal close-coupling calculations on fine structure transitions in rubidium-neon collisions

摘要: Fully quantal close-coupling calculations of the cross sections for fine structure and depolarization transitions in Rb(S2P)-Ne collisions are presented. The proceed by analogy with collision-induced rotational excitation (Reid Dalgarno (1970)). They were performed using interaction potentials Baylis (1969) Hidalgo Geltman at both high low energy. Hidalgo-Geltman potential compared semi-classical found to be reasonable agreement. gives good agreement experiment low-energy inelastic section. Improvement repulsive should improve high-energy results. results suggest that Nikitin's second mechanism (1967) (Coriolis coupling between Pi quasi-molecular states short interatomic distances) is favoured over first (coupling 1/2 Sigma intermediate Rb-Ne collisions.
