利用泵浦探测技术结合库仑爆炸过程的符合动量成像，对CS2 2 2+在强激光场（60 fs，0.13 PW/cm 2）中形成的原子核波包的时间演化进行了真实的跟踪.在133 fs ~ 3 ps的抽运-探测时间延迟范围内，碎片离子间的动量关联表明，CS2 2+的原子核波包不仅沿着反对称伸缩坐标演化产生S+和CS+，而且沿着对称伸缩坐标演化导致两个C-S键同时断裂.具有弯曲和线性型几何构型的两种不同的电子态的贡献被确定在波包运动沿着弯曲坐标的CS2 2+。
The temporal evolution of the nuclear wave packet of CS2 2+ formed in an intense laser field (60 fs, 0.13 PW/cm2) is traced in real time by the pump-and-probe technique combined with coincidence momentum imaging of the Coulomb explosion process, CS2 3+-->S+ + C+ + S+. The momentum correlations among the fragment ions obtained as a function of the pump-probe time delay between 133 fs to 3 ps reveal that the nuclear wave packet in CS2 2+ evolves not only along the anti-symmetric stretching coordinate to yield S+ and CS+ but also along the symmetric stretching coordinate leading to the simultaneous breaking of the two C-S bonds. The contribution from two different electronic states having bent and linear-type geometrical configurations is identified in the wave packet motion along the bending coordinate of CS2 2+.
