The observables are calculated in the one-neutron exchange approximation, for the special case of backward scattering ($θ_{c.m.} = 180^{\circ}$). Several new relations between polarization observables of the reaction are derived within the framework of this approximation.11 pages, LaTeX, Kiev, Bogolyubov Institute for Theoretical PhysicsHigh Energy Physics - PhenomenologyPolarization observables of the $\vec{d} \vec{p} \rightarrow \vec{p}d$ reaction and one-neutron-exchange approximationtext
