Abstract
The dependences of photoionization cross section on incident photon energy and electron emission on polar exit angle are used to determine the location of chemisorption sites. Calculations are made for the S-Ni(001) and CO-Ni(001) systems. Comparing with experiment, it is found that angle-resolved ultraviolet photoelectron spectroscopy data are very sensitive to the coordination number of the adsorption site and less sensitive to the overlayer-substrate interlayer spacing.
