利用全反射现象控制光解离支化：应用于HI分子
Control of photodissociation branching using the complete reflection phenomenon: Application to HI molecule
摘要：
利用全反射现象，可以有效地实现双原子分子光解离分支的激光控制。这种现象和控制条件可以很好地用半经典（Zhu-Nakamura）理论来表述。该方法被施加到分支之间的I（$^2 P_{3/2}$）（HI $\to$ H + I）和I $^*(^2 P_{1/2})$（HI $\to$ H + I $^*$）的形成，并几乎完全控制被证明是可能的，通过适当地选择初始振动状态和激光频率，尽管有三个电子激发态参与的事实。相应的波包动力学的数值计算证实了结果。
英文摘要：
The laser control of photodissociation branching in a diatomic molecule is demonstrated to be effectively achieved with use of the complete reflection phenomenon. The phenomenon and the control condition can be nicely formulated by the semiclassical (Zhu-Nakamura) theory. The method is applied to the branching between I($^2 P_{3/2}$) (HI $\to$ H + I) and I$^*(^2 P_{1/2})$ (HI $\to$ H + I$^*$) formation, and nearly complete control is shown to be possible by appropriately choosing an initial vibrational state and laser frequency in spite of the fact that there are three electronically excited states involved. Numerical calculations of the corresponding wavepacket dynamics confirm the results.
