Matt: I have been having problems with the FEFF6 that is distributed with Ifeffit. If I try to run the executable with the feff.inp the TEST directory, it gives the following output ---- copper Calculating potentials and phases... free atom potential and density for atom type 0 free atom potential and density for atom type 1 overlapped potential and density for unique potential 0 overlapped potential and density for unique potential 1 muffin tin radii and interstitial parameters phase shifts for unique potential 0 phase shifts for unique potential 1 Preparing plane wave scattering amplitudes... nncrit in prcrit 9 Searching for paths...
