Abstract
A simplified formalism of evaluating the isospin-violating amplitude of the neutron-proton scattering in terms of the bar phase shifts is presented. The singlet-triplet mixing angles are evaluated for the following effects: electromagnetic contributions, 0 mixing, and neutron-proton mass difference effect in the charged and one-meson exchanges. The possible difference in the polarization of neutrons and protons is estimated for four lab energies: 200, 325, 500, and 750 MeV. NUCLEAR REACTIONS n-p scattering E=25-750 MeV; singlet-triplet transitions, charge symmetry breaking.
