This program calculates the V_(C) model correlation potential for use as a local approximation to the exact correlation/polarization optical potential using the Boronski and Nieminen potential [see Boronski and Nieminen, Phys. Rev. B 34, 3820 (1986), and Gianturco, Mukherjee and Paioletti, Phys. Rev. A 56, 3638 (1997).] This potential is obtained from considering the interaction of a positron with an electron gas, and thus has been used to model positron-molecule scattering. The asymptotic part of the potential has been further modified so that after R_s = 4.0, the potential goes to zero.
