摘要：

Under the classical particle-dynamics simulation, Coulomb explosion of small Xe clusters in an intense femtosecond laser field and energies of the generated particles are studied. Our results show that the average kinetic energy of the generated ions increases with the cluster size. The dependence of the average kinetic energy of the product ions on the number of atoms inside Xe clusters and the change of average ions charge states from different shells of Xe-561 within the interactional time are studied. The oscillation of the mass center of electrons along the direction of the laser electric field is calculated and the time evolutions of the total potential energy and the total kinetic energy of all the product particles are presented here. The total kinetic energy of Xe ions and free electrons are also calculated as functions of the interactional time.
