The plasmon frequencies of a cube shaped metal cluster are calculated by two different methods. Unlike the spherical cluster, which has a single plasmon frequency,\(\omega _p /\sqrt 3 \), the cube has a series of optically active plasmon frequencies. The two dominant peaks appear at frequencies which are considerably lower than that of a spherical cluster.
