摘要：

The line shape of the plasmon resonance in a cold, small sodium cluster (Na8) is calculated taking into account its coupling to the quantal quadrupole fluctuations of the cluster shape. This coupling is found to give rise to a small damping factor (GAMMA/h-omega-1 approximately 0.03, where h-omega-1 denotes the energy centroid and GAMMA the full width at half maximum of the resonance), and to an asymmetric line shape with Gaussian behaviour in the wings.
