Nature of problem:
An analytical solution of dispersion integral relations, linking the real and imaginary part of the nuclear OMP, has been derived for the most common functional forms. The general numerical solution is also presented.
The decomposition of the integrand function using the analytical properties has been used to calculate the dispersive integral in the complex plane. The numerical solution is based on Gauss-Legendre quadrature formulae.
None. If the dispersive integral of the imaginary potential does not have an analytical solution, the general numerical solution can be used.
