A description of the recently installed mouable Polarized Proton Targe (MPT) at the JINR in Dubna is described. This target was acquired from Fermilab. The physics program based on the MPT at Dbna is outlined. (AIP)

Polarization phenomena in backward elastic dp scattering were studied with a view to reconstructing the deuteron wave‐function components. Experimental data disagree with predictions based on the impulse approximation which suggests that the wave function may have more than two components. (AIP)

The tensor analyzing power T20 and the ratio of the polarization of the backward scattered proton to the vector polarization of the incident deuteron, κ0, for the dp backward elastic reaction were measured. The kinetic energy of the deuteron beam was varied between 0.3 and 2.34 GeV; the elastic protons were detected at a fixed 1.7° in the laboratory. The values of T20 and κ0 obtained are different from those obtained in recent studies of the 0° inclusive breakup reaction dp→pX at the same values of the internal momentum variable k calculated in the infinite momentum frame. However the data from these two reactions are almost identical when compared in T20 versus κ0 correlation plots. We discuss similarities and differences observed in the two reactions which, we argue, support the premise that the two reactions are closely related, as their respective impulse approximation graphs suggest.
