N2 - The adsorption of CO on Ru(001) has been studied using a combination of techniques: LEED/Auger, Kelvin probe contact potential changes, and flash desorption mass spectrometry. Adsorption of CO is reversible at temperatures and pressures as high as 700 K and 10-4 Torr, respectively. Two binding states of CO are identified, and isosteric heats determined both from work function changes and from LEED intensity measurements agree well with flash desorption energies. A disordering of the CO layer due to repulsive interactions between neighbors at high coverages is postulated. Electron beam-induced LEED pattern changes are characterized and found to have a high cross section (-7 × 10-17 cm2) at - 110eV.
