Abstract
It is shown that coherent interactions of protons (neutrons) of energy approximately 1 GeV with a polarized nuclear target of length l resul ts in the rotation of the spin of incident particles through the angle sic = (10(-3) - 10(-4)l (cm). Experimental measurement of this angle makes it possible to directly reconstruct the real part of the spin-de pendent amplitudes of pn and pp forward scattering. It is proposed tha t this effect be used for investigating resonance states in the interm ediate energy range.
