中文摘要：

反应回声是在化学动力学研究的一个边疆话题，并且它对基本化学反应的机制的理解也必要。这篇短文章在研究的边疆描述重要开发。回声处于一个完整的量状态被检测了的反应的试验性的证据解决了 F+H_2 反应的反应散布学习。高度精确的完整的量散布理论建模证明在那里，行动回声由二个 Feshbach 回声状态被引起。量干扰在二回声之间是在场的进一步的研究表演为前面的散布产品说。Thisstudy 在我们在基准 F+H_2 系统的化学反应回声的理解向前是重要的步。动态回声上的 H_2 旋转刺激的效果上的进一步试验性的研究被执行了。在 F+H_2 的动态回声(j= 1 ) 反应也被观察了。

英文摘要：

Reaction resonance is a frontier topic in chemical dynamics research, and it is also essential to the understanding of mechanisms of elementary chemical reactions. This short article describes an important development in the frontier of research. Experimental evidence of reaction resonance has been detected in a full quantum state resolved reactive scattering study of the F＋H2 reaction. Highly accurate full quantum scattering theoretical modeling shows that the reaction resonance is caused by two Feshbach resonance states. Further studies show that quantum interference is present between the two resonance states for the forward scattering product. This study is a significant step forward in our understanding of chemical reaction resonance in the benchmark F＋H2 system. Further experimental studies on the effect of H2 rotational excitation on dynamical resonance have been carried out. Dynamical resonance in the F＋H2 （j = 1） reaction has also been observed.
