“…At the same time we see that the predictions of the model are twice as low as the experimental points [12] in the region where A-isobar is on-mass-shell. In addition, beyond this region the predictions of the model are ambiguous accurate up to factor of 2 due to the ambiguities caused by off-shell behaviour of ~NA-vertex functions.…”

Contribution of A-resonance mechanism to elastic backward pd-scattering over T o = 0.5-0.8 GeV range of incident energy is analyzed. As distinct from [1-3], the parameters of NN~NA amplitudes in the phenomenology of one-meson 7c-and p-exchange are determined from pp~pn~ + reaction immediately in the kinematic region where the process pd~dp occurs. It has been found as a result that in the vicinity of the region where A-isobar is present on-mass-shell, the coherent sum of the amplitudes of A-resonance mechanism, relativistic one-nucleon exchange and single scattering predicts the pd ~ dp cross-section to be twice smaller than the experimental one and does not describe the tensor polarization of t2o deuteron. Possible causes of this discrepancy as well as the relation between the mechanisms of pd~dp process and the data on reactions of quasi-elastic knock-out of fast deuterons by protons (p, pd) from light nuclei, are discussed.

The deuteron-proton elastic scattering has been studied in the multiple scattering expansion formalism. The essential attention has been given to such relativistic problem as a deuteron wave function in a moving frame and transformation of spin states due to Wigner rotation. Parameterization of the nucleon-nucleon t-matrix has been used to take the off-energy shell effects into account. The vector, A y , and tensor, A yy , analyzing powers of the deuteron have been calculated at two deuteron kinetic energies: 395 MeV and 1200 MeV. The obtained results are compared with the experimental data. : 21.45.+v, 25.45.De, 24.10.Jv, 24.70.+s PACS

“…[12], deuterons scattered at θ d lab = 7.5 • from a hydrogen target were selected by the two-arm magnetic spectrometer ALPHA, from the deuterons of other reaction channels and other particles. The same method has been applied recently at COSY using the ANKE spectrometer [15] at the initial deuteron energy of 1170 MeV and 4 • ≤ θ d lab ≤ 10 • where the vector and tensor analyzing powers are large [13,16].…”
