✦ Synopsis

The rate of linear collisionless damping (Landau damping) in a classical electron gas confined to a spherical ionized cluster irradiated by an intense laser pulse is calculated. The expression for the energy absorbed by the cluster from the laser pulse is obtained in terms of the parameters of the self-consistent single-electron potential. It is explicitly calculated as a function of the electron temperature for the case when the self-consistent potential is modelled by an infinitely deep spherical rectangular well. On this basis the rate of collisionless heating and the width of the linear Mie resonance are estimated for realistic experimental parameters. Recommendations for unambiguous observation of Landau damping in laser-irradiated clusters are formulated. 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0.5 1.0 1.5 2.0 2.5 3.
