Aa. Pavlychev et Ng. Fominykh, CHEMISORPTION EFFECT ON K-SHELL XANES IN N-2 AND CO MOLECULES ON SURFACES, Physica. B, Condensed matter, 209(1-4), 1995, pp. 449-450
Using the quasi-atomic approach the appearance of a new sigma-resonanc
e feature in K-shell XANES of diatomic adsorbates due to their chemiso
rption is shown.
