Description

At an Internal Target Station at the JINR Nuclotron, dp elastic data were collected using a polarized deuteron beam from a brand-new polarized ion source. To make predictions, a relativistic multiple scattering model is employed in the energy range 400-1800 MeV. While the relativistic scattering model using delta-isobar excitation mechanism properly describes the cross section and vector analyzing power Ay for energies below 1000 MeV, the tensor analyzing powers do not match the theoretical expectations. Additional mechanisms may be the cause of difference at higher energies. Generally, the isoscalar nucleon-nucleon interactions are sensitive to the short-range spin structure, as demonstrated by cross sections and deuteron analysis powers in measured energy range. Results of the dp breakup reaction at 300 MeV using several detector configurations will be given. Data has been collected in the energy range from 300 to 500 MeV of incoming deuteron.
