ROMPIN — A relativistic optical model program for pion-nucleus scattering

Abstract Pion-nucleus elastic scattering and single- and double-charge exchange to analog states are computed from a momentum- space optical potential. The optical potential is calculated with an exact performance of the fermi averaging integral and with fully relativistic kinematics by utilizing relativistic three-body recoupling coefficients.
