PARSEC requires pseudopotential input files. We recommend the norm-conserving pseudopotentials designed by Prof. J. L. Martins. Details of his construction method can be found here.
To expedite the use of these pseudopotentials, we have prepared a library of potentials that can be directly input in PARSEC.  The format will be consistent with the input required from PARSEC.  Sometimes multiple potentials are offered for an element.   You can get them by clicking on the element in the following.  The output is a zipped file with text files.
