T hus, the formal structure is analogous to that of nonreactive (inelastic) scattering. All the calculations done recently for collinear systems with smooth, realistic potentials are based on equation (78) and the physical transition amplitudes are computed using the arrangement channel generalized damping relation equation (76).
