The study of electronic energy spectroscopy for nitrogen adsorption

4 The study of electronic energy spectroscopy for nitrogen adsorption 

The similar Auger spectrum was detected for the N2 adsorption on W (110) at 100 K. The amount of adsorbed dinitrogen can be estimated from the height of Auger spectroscopy peak such as 390 eV peak for W (Ref. 48) and 380eV peak for Fe. 

It is commonly accepted that the atomic adsorption nitrogen could form peaks at about 400 eV. For example, the adsorbed N on W at 300 K has two peaks at 397.2 eV and 398.0 eV, one peak at 397.2 eV on Fe at 290 K, and one peak at 397.5eV on Fe with promoter at 673 K. The surface reconstruction caused by nitrogen adsorption was observed for many metals.
