However you have referred particularly to the scattering amplitude dependence on the interatomic distance. How about the phase shift, which seems to depend strongly on the this variable?
The function that describes the scattering of the photoelectron is a *complex* function. It has an amplitude and a phase. For the WHOLE story: Rehr and Albers, Rev. Mod.
