The differential cross section in deuteron-proton elastic scattering at 500, 750 and 900 MeV/nucleon

The results on the differential cross section of dp elastic scattering obtained at the Internal Target Station at the Nuclotron JINR at the energies of 500, 750 and 900MeV/ nucleon are presented. The measurements have been performed using an unpolarized deuteron beam and polyethylene foil target. The data have been obtained in the angular range of 70 degrees-120 degrees in the cms. The angular dependences of the data from the present experiment are compared with the world experimental data obtained at nearby energies as well as with the theoretical calculations performed within the relativistic multiple scattering theory. The behavior of the differential cross section at the fixed scattering angles covering the total cms energy region of root s = 3.1-3.42 GeV is in qualitative agreement with the s power-law dependence.
