  A Green's function formalism is used to calculate the spectrum of excitations
of two neighboring impurities implanted in a semi-infinite ferromagnetic. The
equations of motion for the Green's functions are determined in the framework
of the Ising model in a transverse field and results are given for the effect
of the exchange coupling, position and orientation of the impurities on the
spectra of localized spin wave modes.
