Abstract

A field‐theoretical formalism is applied to the problem of atom–diatom scattering, in the presence of “intermediate” reactive channels. This leads to an integral equation formulation for elastic processes and to a numerical quadrature problem for inelastic vibro–rotational transitions. The key quantity of the theory is represented by an effective potential that contains full information on the dynamics of the process. A closed equation is obtained for this quantity, along with an approximation scheme of the second order in the system interaction potential. A diagrammatic technique is introduced and the physical interpretation of the approximate form of the effective potential considered.
