✦ Synopsis

The dynamical Lie algebraic approach developed by Y. Alhassid and R. D. Levine (Phys Rev A 1978, 18, 89) combined with the intermediate picture is applied to the study of translational-vibrational energy transfer in the collinear collision between an atom and an anharmonic oscillator. By solving equations of motion for the group parameters under the first-order approximation of the group parameters, we calculate the vibrational transition probabilities of anharmonic molecule scattering with an atom in the intermediate picture. Numerical test calculations are carried out for the collinear scattering system HBr + He; the results show that the dynamical Lie algebraic approach can be useful for the description of atom-molecule collision phenomena.
