摘要：

We have observed for the first time two Tamm-type surface states on the (001) and (100) surfaces of equi-atomic CuAu I, at binding energies of about 1.5 eV and 6.2 eV. By measuring their dispersions in k(parallel to)-space we have located symmetry points in the surface Brillouin zones, which has enabled us to deduce the lattice spacings in the surface layer. We find that these values are very similar to those of the bulk. Copyright (C) 1996 Elsevier Science Ltd.
