Abstract: The excited states of the snrface optical phonon bounded to an impurity atom centred on the surface is calculated by means of the variational priciple. It is found that the effect of the SO-phonon is significant even on the excited state energy.

Key words: surface impurity, surface optical phonon, excited state
