Abstract

The fluxes across the phase-space bottlenecks are treated in the first order of classical perturbation theory and simple formulae are derived for the bottlenecks formed by broken quasiperiodic and homoclinic orbits. These formulae are applied to the model problem of HeI2 vibrational predissociation and good agreement between the first-order and exact fluxes across unperturbed bottlenecks is found. Perspectives of the first-order approach in the framework of the kinetic description of phase-space transport are drawn.
