通过求解含时薛定谔方程,提出了利用三束激光脉冲控制H+2解离以及解离过程中电子位置的方案.第一束阿秒激光脉冲将H+2从1sσg激发至2pσu,在H+2的解离过程中,引入两束波长分别为800 nm与400 nm的飞秒激光脉冲控制电子在分子内部的运动.通过改变两束激光脉冲的绝对相位, H+2解离后电子的位置可以得到有效控制(最大有86%的概率使得电子附着在某一个原子核上).现有的激光技术条件可以在实验上实现这一理论方案.

@@@@We study the control of electron localization in the dissociation of H+2 using three laser pulses by numerically simulating the time-dependent Schr¨odinger equation. First, we use an attosecond pulse to excite the wave packet of H+2 from 1sσg to 2pσu. Then, two-color femtosecond pulses (800 nm+400 nm) are used to control the dissociation of H+2 . By manipulating the phases of two femtosecond pulses, the electron localization can be controlled effectively. For the proper laser parameters, the maximal probability that the electron is located on the selective nucleus is up to 90%. This theoretical scheme can be realized by the state-of-art laser technology.
