摘要
Rotational invariance is applied to the description of atom-diatom collisions in a translational-internal coupling scheme, to obtain energy sudden (ES), centrifugal sudden (CS), and infinite order sudden (IOS) approximations to the reduced scattering S matrix S(j̄λ̄;L;jλ). The method of presentation emphasizes that the translational-internal coupling scheme is actually the more natural description of collision processes in which one or more directions are assumed to be conserved. © 1979 American Institute of Physics.
