    "abstract": "The periods of the harmonic oscillations of the ion core of charged sodium\nclusters around the equilibrium shapes are considered. It is found that these\nperiods are of the order of magnitude of the experimentally measured relaxation\ntimes of the plasmons, which suggests the importance of the electron-ion\ncoupling and stresses the role played by the electron-phonon interaction in the\ndissipation of the plasmon energy. The relation of the process to fission is\nbriefly discussed.",
