We analyze the effect of electron-electron collisions in the electronic dynamics of sodium clusters using the Vlasov-Ühling-Uhlenbeck approach. The damping rate due to two-body collisions follows the expected quadratic-in-temperature trend and complies with estimates from Landau liquid theory and is hinted at in the first experimental results.
