摘要
The recently developed plane wave packet method is applied to the F + HD reaction on the Stark-Werner potential surface, yielding converged differential cross-sections (d.c.s.) over the collision energy range E = 0-0.15 eV. A wave packet 'movie' is obtained showing how the HF product scatters into space. Two direct and two time-delayed mechanisms are observed. One of the latter corresponds to a recently observed Feshbach resonance. The movie is related to the energy-dependent d.c.s. by a time-dependent d.c.s., which reveals quantum interference between the direct and time-delayed mechanisms. (C) 2003 Elsevier Science B.V.
