Abstract :
Coulomb explosion of fullerene, benzene and proton cluster induced in an interaction with an intense femtosecond laser pulse has been investigated with the use of MD and PIC simulations. Simulations reveal different ionization processes in the large molecules and an acceleration mechanism of GeV protons in the cluster.
