Abstract:

The interaction between C₆₀ clusters and dense plasmas has been studied using the molecular dynamic simulation (MDS). In the framework of linearized Vlasov-Poisson theory, the analytical expression of stopping power of the cluster is obtained with the classic plasma dielectric function. The Coulomb explosions of the cluster are studied by solving the motion equations. The effect of projectile velocity, plasma density and electron temperature on stopping power and Coulomb explosion of the cluster are discussed, respectively. The results show that the wake effects can reduce the speed of Coulomb explosions, and even stabilize the cluster structure, the Coulomb explosion will proceed faster in the situations of high velocity, low plasma density or high plasma temperature.
