Feff calculation
WebA FEFF calculation starts with two basic tasks: calculation of the potentials, followed by calculation of the scattering phase shifts. Using these phase shifts, scattering paths are found and their scattering amplitudes calculated. http://monalisa.phys.washington.edu/feffproject-feff-documentation.html

Webfeff is designed to calculate absorption from completely filled shells. You can try to simulate absorption from valence electrons with feff, but you may get unreliable results. If you encounter difficulties and need valence shell absorption, please contact the authors. Webfeff uses an ab initio self-consistent real space multiple scattering (RSMS) approach, including polarization dependence, core-hole e ects, and local eld corrections, based on …

WebMay 4, 2010 · In the case of S02, this parameter is a measure of the non-unity overlap of the electronic states of the absorbing atom before and after the creation of the core-hole. That is, it is somehow a measure of the relaxation of the electrons in the presence of the core hole. As such, we expect S02 to be a number around, but smaller than, 1. WebFEFF Input × Warning: These ... Tasks (calculations) with bold text have the lowest final energy per atom output amongst all tasks with the same task type for this material. These "blessed" tasks are used for higher-level analysis. The VASP user-specific input and output files for these "blessed" tasks can be downloaded from NOMAD.
