摘要：
The explosion dynamics process of heteroclusters ((CH4)n, (CD4)n, (D2O)n) in ultraintense femtosecond laser fields has been studied theoretically using Bethe model. It is found that the average energy of hydrogen ions and deuterium ions after explosion has a linear relationship with the square of initial cluster radius, and the explosion mechanism is typical Coulomb explosion. Furthermore, the deuterium ions from the heteroclusters have higher energy than those from the homonuclear clusters ((D)n), indicating that highly ionized ions of high Z element have a strong acceleration effect on the ions of low Z element.
