Optimisation of the non-geometric parameters led to very good agreement between experimental and theoretical IV-curves and hence to a high accuracy in the structural parameters. In agreement with earlier work atomic oxygen is found to adsorb on fcc sites in both structures. In the co-adsorbed phase CO occupies atop sites. The positions of the substrate atoms are almost identical, within 0.02Å, in both structures, implying that the interaction with oxygen dominates the arrangement of Ni atoms at the surface. © 2004 Oldenbourg Wissenschaftsverlag GmbH Thermodynamics & statistical physics nationallicence Laboratory techniques, experiments nationallicence Physical chemistry nationallicence Braun Wolfgang aut Steinrück Hans-Peter aut Held Georg aut Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/8/2004(2004-08-01), 915-927 0942-9352 218:8/2004<915 2004 218 zpch https://doi.org/10.1524/zpch.218.8.915.35977 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/zpch.218.8.915.35977 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Braun Wolfgang aut NATIONALLICENCE 700 1- Steinrück Hans-Peter aut NATIONALLICENCE 700 1- Held Georg aut NATIONALLICENCE 773 0- Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/8/2004(2004-08-01), 915-927 0942-9352 218:8/2004<915 2004 218 zpch CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
