用含时黄金规则波包法计算了ＨｅＩＣｌｖａｎｄｅｒＷａａｌｓ络合物分子的振动预离解寿命和离解碎片ＩＣｌ的终转动态分布。并与实验和其他理论计算结果做了比较。波包计算所用的总传播时间（不超过１ｐｓ，远小于离解寿命）实际上是解离碎片在振动退激发绝热势能面上的滞留时间。终态相互作用对终转动态分布起着决定性作用。并预言了ＨｅＩＣｌ终转动态分布对振动态的依赖。 The vibrational pre-dissociation life of HeIClvanderWaals complex molecule and the final kinetic distribution of dissociated fragment ICl were calculated by the time-dependent golden rule wave method. And compared with the experimental and other theoretical calculations. The total propagation time (no more than 1 ps, much less than the dissociation life) used for wave package calculation is actually the residence time of the dissociated fragments on the adiabatic potential surface of the vibration-induced retreat. The final state interaction plays a decisive role in the final dynamic distribution. And predicts the dependence of dynamic distribution of HeICl on the vibrational state.
