Study of T-odd asymmetry in backward elastic dp scattering as a method to identify the reaction mechanism

Recent measurements of the polarization observables in the dp → pd reaction at Dubna and Saclay have shown that a consideration of this reaction in the framework of the one nucleon exchange mechanism is inadequate. The T-odd effects due to the polarization of both colliding particles are considered. It is shown that the new polarization observable is especially sensitive to the mechanism of the reaction. The paper is inspired by the fact that a polarized proton target, which can provide a polarized deuteron beam, is now installed at the Dubna synchrophasotron.
