The simple qualitative method for treating electronic correlation in crystal surfaces, suggested recently by the author and by Davison and Amos, is discussed in detail. As an example, a study is made of the effect of interelectronic repulsion on the behaviour of electrons localized near an ideal (100) surface of a diamond‐like crystal. The spin‐degeneracy of the electron surface states is found to be split and possible physical consequences of this splitting are mentioned. Surface states lying in “forbidden” bands differ from volume states in their sensitivity to the magnitude of the volume state energy bands seem to have the same sensitivity to the interelectronic repulsion as the volume states.
