计算了超短强激光脉冲与团簇气体相互作用形成的球对称带电团簇库仑爆炸的粒子分布函数。得到了加速粒子的密度分布、平均速度分布和能谱。这些特性进行了详细的分析冷集群等离子体，其中的动力学效应确定的物理多个流出现后，集群粒子的速度分布的营业额。我们找到了多流区的边界，并研究了爆炸团簇作为其初始密度分布函数的特性。对于具有特定团簇尺寸分布的团簇等离子体，得到了加速离子的能谱。
The particle distribution function is calculated for the Coulomb explosion of a spherically symmetric charged cluster formed through the interaction of intense ultrashort laser pulses with a cluster gas. The particle density and mean velocity distributions as well as the energy spectra of the accelerated particles are obtained. These characteristics are analyzed in detail for a cold cluster plasma, where the kinetic effects determine the physics of multiple flows emerging after the turnover of the cluster particle velocity profile. We find the boundaries of the multiple-flow regions and study the characteristics of an exploding cluster as a function of its initial density profile. The energy spectra of the accelerated ions are obtained for a cluster plasma with a specified cluster size distribution.
