7.5 Pseudopotential file: xx pp.data<br />
casino can carry out all-electron or pseudopotential calculations, but it is normally advantageous<br />
to replace the core electrons by a pseudopotential. casino will automatically treat an atom as allelectron<br />
unless there exists a pseudopotential file xx pp.data in the directory in which casino is run,<br />
where xx is the symbol for the element in question in lower case. This file contains the different angular<br />
momentum components <strong>of</strong> the pseudopotential given on a radial grid and some auxiliary information<br />
in the following format:<br />
LSDA Pseudopotential in real space for Si<br />
Atomic number and pseudo-charge<br />
