Abstract : The S matrix for inelastic and rearrangement collisions derived within Feshback's theory of resonance can be written as the sum of SD and SC, where SD refers to direct interaction processes, and SC refers to complex (Resonant) processes. For collision times short compared to characteristic times of internal motions of reactants, models of direct interactions, which assume SC to be zero, have been developed. For collision times long compared to all characteristic times of internal motion, statistical models of complex formation, which assume SD to be zero, have been formulated. A possible method is examined for making quasistatistical (or partial statistical) approximations on SC (for inelastic and reactive scattering). Possible deductions from the various experiments are discussed and examples of reactions for the different categories are cited. (Author)
