Program vcppol

This program calculates the V_(C) model correlation potential for use as a local approximation to the exact correlation/polarization optical potential using the Perdew-Zunger potential [J. P. Perdew and A. Zunger, Phys. Rev. B 23, 5048 (1981). and N. T. Padial and D. W. Norcross, Phys. Rev. A 29, 1742 (1984).].
