摘要：

采用经典理论的辛算法数值求解强场下二维共面异核氢分子离子(HD⁺)的Hamilton正则方程, 得到了二维异核氢分子离子(HD⁺)在激光场作用下的经典轨迹, 计算了HD⁺的存活几率、电离几率、解离几率、 Coulomb爆炸几率及相应的电子位置与核间距随时间的演化, 并分析了单色场强度变化对HD⁺动力学行为的影响, 将HD⁺与同核氢分子离子（H⁺₂）的动力学行为进行比较, 给出了物理解释.

Abstract:

The symplectic method of classical theory was used to solve numerically the Hamilton canonical equations of the 2D planar HD⁺ in intense laser fields, and obtained the classical trajectories of the 2D planar HD⁺ in the laser fields, the probabilities of survival ionization, dissociation, Coulomb explosion and the average distances from electron to the mass-center for various laser parameters as functions of time were investigated. We analyzed intensity dependence on the dynamics of HD⁺ in the monochromatic laser fields and compared our results with the corresponding H⁺₂ calculations and gave the corresponding physical explanations.

Key words: two-dimentional HD⁺, classical dynamics, symplectic method, intense laser field
