摘要:

本文报道了对典型的S(^1D_2)+H_2插入反应的综合研究。动力学和交叉束实验接近冷能制度的实验条件下进行,产生的绝对速率系数下降到5.8 K和相对积分截面碰撞能量低至0.68毫电子伏。它们得到了精确处理长程相互作用的势能面上的量子计算的支持。所有的结果是一致的,激发函数的行为解释的各种分波的累积贡献。

英文摘要:

We report combined studies on the prototypical S(^1D_2) + H2 insertion reaction. Kinetics and crossed-beam experiments are performed in experimental conditions approaching the cold energy regime, yielding absolute rate coefficients down to 5.8 K and relative integral cross sections to collision energies as low as 0.68 meV. They are supported by quantum calculations on a potential energy surface treating long range interactions accurately. All results are consistent and the excitation function behavior is explained in terms of the cumulative contribution of various partial waves.
