Abstract

Scattering in a highly excited van der Waals complex He-I-2 is investigated in quantum mechanics. Particular attention is paid to crisis, where homoclinic tangency of the stable and unstable manifolds leads toa transition in chaos. Crisis in classical chaos gives rise, in the corresponding quantum system, to multiple decay paths with distinct decay times. The resulting effects are nonexponential decays in the predissociation processes and a transition in the distribution of final rotational states. Implications of these results for control of reaction processes are briefly discussed.
