摘　　要：通过理论模拟氢分子离子处在高振动态下的库仑爆炸核初始动能释放谱,详细地研究了强场中氢分子离子在相应振动态的电荷共振增强电离过程.计算结果表明:振动态为υ=5的电荷共振增强电离过程和振动态为υ=6、7的电荷共振增强电离过程是不相同的.The charge-resonance-enhanced ionization of the molecular ion H＋2 for high initial vibrational states in intense laser field is theoretically investigated by analyzing the Coulomb explosion nuclear initial kineticenergy-release spectra.The results confirm that compared with the process of the charge-resonance-enhanced ionization of H＋2 for the initial vibrational state υ = 5,it is different for the initial vibrational states υ = 6 and 7.
