Classical Theoretical on Two-Dimensional Hydrogen Molecular Ion (HD^+) in Intense Laser Fields

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(H2+)的动力学行为进行比较,给出了物理解释.

The symplectic method of classical theory was used to solve numerically the Hamilton equations of the 2D planar HD ＋ in intense laser fields, and obtained the classical trajectories of the HD ＋ in the laser fields, the probabilities of survival ionization, dissociation, Coulomb explosio average distances from electron to the mass-center for various laser parameters as functions of canonical 2D planar n and the time were investigated. We analyzed intensity dependence on the dynamics of HD ＋ in the monochromatic laser fields and compared our results with the corresponding H2＋ calculations and gave the corresponding physical explanations.
