This is a binary file with the scattering phase shifts for each unique potential. It is used by GENFMT and the pathfinder.
Written by the pathfinder, this is a description of all the paths that fit the criteria used by the pathfinder. It is used by GENFMT. The path descriptions include cartesian coordinates of atoms in the path, scattering angles, leg lengths and degeneracy. For details on editing this by hand, see section 4.
Values of the quantities tested against the various criteria in the pathfinder.
Written by feff for use with the pathfinder, and deleted after use. It is an atom list created from the user-input list in feff.inp. For more information, see the NOGEOM card in section 4.
List of files to use to create chi.dat. Written by GENFMT when the xafs parameters are calculated and used by FF2CHI. This contains the curved wave importance ratios, which you may wish to study. For details on editing this by hand, see section 5.
Standard xafs data k, chi(k), |chi(k)| relative to threshold (k=0): The header also contains enough information to specify what model was used to create this file.
Effective scattering amplitude and phase shift data, with k referenced to threshold for shell nn: k, phi_c, |feff|, ph(feff), redfac, lambda, Re(p)
Header file for quick reference.
Complex phase shifts for each shell.
Detailed atomic potentials and densities.
Diagnostic information on Desclaux free atom NN.
Dipole matrix elements and absolute energies for XANES calculations. Note: the file xsect.bin does not contain the fermi-function cutoff at the edge, while xmu.dat does. The file xmu.dat contains both XANES and XAFS data mu, mu_0, and chi as functions of absolute energy E, relative energy E-e_f and wave number k.
