计算了超强超短激光脉冲照射的大型碘化氢团簇的内部和外部势垒上电离以及库仑爆炸的动力学。我们发现，与水动力相比，库仑力在这些团簇的膨胀中占主导地位。推导了碘多原子离子在激光焦体积内的能量分布。我们的计算结果与 Tisch 等人最近的实验数据非常吻合。 [物理。 Rev. A 60, 3076 (1999)]。
Dynamics of the inner and outer above-barrier ionization and of the Coulomb explosion are calculated for large hydrogen iodide clusters irradiated by superintense ultrashort laser pulses. We have found that the Coulomb forces predominate in the expansion of these clusters in comparison with the hydrodynamic forces. The energy distribution of the iodine multiple atomic ions in laser focal volume is derived. Results of our calculations are in a good agreement with the recent experimental data of Tisch et al. [Phys. Rev. A 60, 3076 (1999)].
