We have studied the surface resonances on MO(100) and W(100) with angle-resolved, h..omega..-dependent photoemission using synchrotron radiation. For normal emission, two resonances are seen. They are located 0.3 and 3.3 (0.4 and 4.2) eV below E/sub F/ for Mo (W). The high-lying resonance remains symmetric and narrow for all photon energies used. Its intensity peaks at h..omega.. = 15 and 30 (14 and 29) eV for Mo (W). For theta > or = 2/sup 0/, a second high-lying resonance appears a few tenths of an eV below the first one. Many-body phenomena are not required to explain the data.
