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 />
