A working procedure for the evaluation of exafs phase shifts : application to Cu(111)/Cs

• A theoretical procedure is presented to evaluate EXAFS phase shifts. The procedure is based on a self-consistently determined ground-state electron density and an energy-dependent complex scattering potential. Most EXAFS or NEXAFS/XANES schemes used today apply a constant imaginary part of the scattering potential. We illustrate our procedure by calculations on cesium atoms adsorbed onto Cu(111).
