2x10(3) 至 4x10(4) Ar 原子簇在强激光场（高达 8x10(15) W cm(-2)）中发生库仑爆炸。探讨了多电荷氩离子能量对光偏振态的依赖性。对于最高电荷态，观察到离子爆炸能量的方向不对称性。离子能量分布由低能各向同性成分和高能各向异性成分组成。结果根据不对称库仑爆炸场景进行讨论。
Clusters of 2x10(3) to 4x10(4) Ar atoms are Coulomb exploded in intense (up to 8x10(15) W cm(-2)) laser fields. The dependence of multiply charged argon ion energies on the polarization state of light is probed. A directional asymmetry in the ion-explosion energies is observed for the highest charge states. The ion-energy distribution consists of a low-energy isotropic component, and a high-energy anisotropic one. The results are discussed in terms of an asymmetric Coulomb-explosion scenario.
