摘要：

The structural parameters of the (square-root 3 x square-root 3)R30-degrees overlayer formed by N2 adsorption on Ru(0001) have been determined by a LEED IV analysis. The N2 molecules are coordinated to the surface at on-top sites with the interatomic axis perpendicular to the surface. The N-N bond length turns out to be 1.10 +/- 0.04 angstrom which equals the bond length of gaseous N2. The interaction of N2 with Ru (0001) is characterized by a lack of pronounced substrate distortions.
