Abstract
A relativistic formalism of the scattering including the electromagnetic contributions is presented. Relativistic electro- magnetic phase shifts are defined and evaluated. The difference between the nuclear phase shifts of the and interactions is evaluated taking into account the interference between strong and Coulomb forces, electromagnetic contributions and the mass differences between the charged and neutral pions. The interaction is described with the aid of six amplitudes. Neutron- proton observables are calculated with these six amplitudes. The mixing angle of the singlet-triplet transitions is evaluated. Experiments which should show these transitions are discussed.
