Title of program: PIRK Catalogue Id: ABCJ_v1_0 Nature of problem Angular distributions for the elastic scattering of pions from optical potential representations of the nucleus are generated from the partial wave expansion of the scattering amplitude. Complex phase shifts for each partial wave are obtained by numerically integrating the radial Klein-Gordon equation in the interior region and matching to the asymptotic Coulomb wavefunction in the exterior region. The integration is done using the fourth-order Runge-Kutta method. To insure accuracy, the program ...
