Abstract
A model accounting for the time dependence of shape fluctuations in metal microclusters and their effect on the damping width of the plasmon resonance is discussed. An estimate of the relaxation time of the quadrupole shape is given, and calculations demonstrating the effects of time-dependent thermal fluctuations on the plasmon in K +9 are presented.

We note that this assumption is reasonable for lighter clusters (i.e. Na8) and positively charged clusters, such as K + N , as the plasmon resonance is highly collective and is dominated by a single peak representing vibrations along the principal axes [6]
