This card roughly simulates the effect of complete core-hole
screening. It is useful to test the final state rule for
calculated XAS, and to compare with other calculations (such as band
structure or other codes) that do not have a core hole.
The code will use the final states specified by the HOLE or EDGE card
for the matrix element calculation -- the NOHOLE card will cause
FEFF to calculate potentials and phase shifts as if
there is no core-hole. For DOS and or
absorption calculations, for example, NOHOLE often gives better
agreement for white line intensities. Conversely NOHOLE tends to give
poor XANES intensities for K-shell absorption in insulators.
