摘　　要：本文通过数值求解非玻恩-奥本海默近似下的一维含时薛定谔方程模拟了强场中初始振动态对H_2^+解离过程的影响.结果表明:不同初始振动态H_2^+的对应的核动能谱结构不同.低振动态时解离过程主要由阈上解离通道贡献,振动态提高时会增加一个键的软化通道.In this paper, we have simulated the effect of the initial vibrational state on the dissociation process of H2＋ in intense field by numerically solving the one-dimensional non-Born-Oppenheimer approximation time-dependent Schr？dinger equation. The results show that the kinetic energy release spectra structures are different for H2＋ at different vibrational states. For the lower vibrational state, the above-threshold dissociation mainly contributes to the dissociation process, while for the higher vibrational state, the bond-soften channel also contribute to the dissociation process besides the above-threshold dissociation.
