difficult to say. Pseudopotentials have a limited energy range of good transferability (but not so limited: a few Ry around the reference energy). They may have ghosts states at high energies (where nobody will notice except you). The higher the energy, the more your bands will be free-electron-like and the less the pseudopotential will be important, though. Paolo -- Paolo Giannozzi, Democritos and University of Udine, Italy
