| 英文摘要 | crossed molecular beam experiments and accurate quantum dynamics calculations have been carried out to address the long standing and intriguing issue of the forward scattering observed in the f + h2 -> hf(v' = 3) + h reaction. our study reveals that forward scattering in the reaction channel is not caused by fesh-bach or dynamical resonances as in the f + h-2 -> hf(v = 2) + h reaction. it is caused predominantly by the slow-down mechanism over the centrifugal barrier in the exit channel, with some small contribution from the shape resonance mechanism in a very small collision energy regime slightly above the hf(v' = 3) threshold. our analysis also shows that forward scattering caused by dynamical resonances can very likely be accompanied by forward scattering in a different product vibrational state caused by a slow-down mechanism. |
