FEFF 8 Example Files

The files linked on this page are the input and output files from example runs of FEFF 8. The input file, feff.inp, contains instructions for running all six modules of FEFF to produce the corresponding spectra.

The descriptions given here are brief, please see the FEFF documentation for additional details.

File Descriptions

feff.inp: This is the input file for the example run.
xmu.dat: This file contains the background function, chi, and the total absorption spectrum.
ldosNN.dat: These files contain the L projected density of states for the absorbing and non-absorbing atoms. The number NN corresponds to the value of ipot in the POTENTIALS card in feff.inp.; This file contains a copy of the information printed out on the screen during the run. The file is useful for diagnostic purposes. (The files log.dat, logN.dat, and logdos.dat contain the same information.)
