Semiclassical theory of rotational and vibrational excitation in collisions of atoms with diatomic molecules. Interim report

Technical Report ·
OSTI ID:6403216
;
A theory of rotationally and vibrationally inelastic collisions in atom-diatomic molecule scattering is presented in which both rotations and vibrations are treated semiclassically. The formalism, however, allows for an unambiguous specification of the initial and final quantum states even though the S-matrix itself is calculated in the classical limit. This development is particularly suited to the description of inelastic collision processes among the highly excited rotational-vibrational states which lie near the continuum. (Author)
