Using the Green function approach the resonance image states at Cu(111), Au(111), and Al(111) surfaces were studied and the distributions of the density of states were calculated in the crystal surface region. It is shown that the crystal lattice potential influences the resonance image states and is responsible for the difference in their binding energies at (111) surfaces of Cu, Au and Al.
