Phase space geometry of chaotic reactive scattering: Gateways, windings, and halos

摘要: We present a renewed geometrical approach to classical reactive scattering. treat here linear triatomic indirect reaction. Geometry in phase space is presented by means of careful analysis the asymptotic motion and its consequences on finite-distance properties. It allows us define gateway reaction probability densities surface section. Because chaos, surrounded windings, whose existence proved. Windings are grouped halos, which statistical repartition reactants assumed. Halos allow whole chaotic scattering simple meaningful way. By measuring areas, we able calculate but realistic model. This computation agrees with averaging over trajectories. {copyright} {ital 1997} The American Physical Society}
