Monolayers of Ns, physisorbed on the Al ( 111) surface at 20 R, were investigated by means of high-resolution electron energyloss speetroseopy (HREELS) and IJV photoelectron spectroscopy (UPS). The N2 stretching vibration at 290 meV is excited by negative-ion resonance scattering. By coadsorption of
