应用经典理论并采用辛算法,计算了HF分子在啁啾激光作用下的经典解离.讨论了激光场中HF分子的解离概率随时间的变化以及考虑振动,转动能级跃迁对分子解离概率的影响,计算结果与理论分析相符,说明运用经典理论并采用辛格式计算双原子分子在激光作用下的经典解离是有效和可行的.
The classical dissociation of a diatomic molecule by chirped laser pulses is evaluated by means of symplectic algorithm. We discuss the effect of the vibro-rotational energy level transition on the dissociation probability.
