The bond geometry of the mixed O + N2-(2 ร— 2) overlayer on Ru(0001) was determined by analyzing low-energy electron-diffraction intensity data. While the oxygen atoms sit in hcp sites, exhibiting a local adsorption geometry similar to that found in the pure 0-(2 ร— 2) phase, the N 2 .molecules occupy
