Abstract : This work aims at studying the influence of electron-electron collisions on the electronic and ionic dynamics of metal clusters, excited by an intense femtosecond laser pulse. We use here a semi-classical description, which replaces the quantum wave-function, representing the the valence electrons of the metal cluster by a distribution function of the phase space. The formal advantage of the semi-classical representation consist in allowing to implement easily, by means of the kinetic equations, the Ühling-Uhlenbeck collision term, to go beyond the mean field description. The dynamic is then given by the Vlasov-Ühling-Uhlenbeck (VUU) equation, which is solved numerically using the test particle method.
