强激光场条件下氘分子离子核动力学的理论研究

Theoretical Study of Nuclear Dynamics of Deuterium Molecular Ions in Intense Laser Pulse

本文通过理论模拟氘分子离子处在不同初始核振动态的库仑爆炸核动能释放谱,详尽地研究了飞秒激光强场条件下氘分子离子在相应初始核振动态下的核动力学过程.计算结果表明:核动能释放谱中的峰值位置在很大程度上依赖于氘分子离子初始核振动态的选取,即氘分子离子在强激光场中的核动力学对其初始核振动态的选取非常敏感.

The coulomb explosion kinetic-energy-release spectra of D2^＋ in various initial vibrational states are theoretically simulated and the nuclear dynamics of D2^＋ in coulomb explosion is investigated. The results show that the peak of the spectrum largely depends on the selection of the initial vibrational states, namely, the nuclear dynamics of D2^＋ in coulomb explosion is sensitive for the selection of the initial vibrational states.
