Abstract
Nitrogen layers adsorbed on W(110) at 100K have been investigated by XPS, UPS and XAES. It is concluded from the results that only one molecular adsobred N//2 species exists, and that the N//2 molecules most probably stand upright on the surface. The core level spectra are characterized by very intense satellites, which is understandable in terms of very recent theories and can be attributed to the very weak adsorption bond. By comparison of UPS and XPS valence band spectra the two adsorbate peaks found can be assigned to levels which are derived from the 1 sigma //u and the pi //u plus 2 sigma //g levels of the N//2 molecule. The adsorption kinetics is characterized by a constant sticking coefficient up to saturation.
