Recent results with polarized deuterons and polarimetry at Nuclotron-NICA
Recent results on the deuteron analyzing powers obtained in collisions of polarized deuterons with protons and light nuclei at intermediate and high energies are reportedye
Spin studies of the short-range correlations at Nuclotron
The results on the angular dependencies of the vector Ay and tensor Ayy and Axx analyzing powers in deuteron-proton elastic scattering at large scattering angles are presented. These data were obtained at internal target at JINR Nuclotron in the energy range 400-1800 MeV using polarized deuteron beam from new polarized ion source. New data on the deuteron analyzing powers in in the wide energy range demonstrate the sensitivity to the short-range spin structure of the isoscalar polarized deutero
Investigation of reactions using polarized and unpolarized deuteron beam at Nuclotron: current status and perspectives
Deuteron induced reactions at intermediate energies are investigated at Internal Target Station (ITS) of Nuclotron. The dp elastic scattering data have been accumulated in the angular range (70◦ - 120◦) in c.m from 0.3 to 2.0 GeV of deuteron energy. Part of the obtained results of differential cross sections and analyzing powers of dp elastic scattering are compared with theoretical predictions based on relativistic multi-scattering mode
First results on the energy scan of the vector Ay and tensor Ayy and Axx analyzing powers in deuteronproton elastic scattering at Nuclotron
New results on the vector A y and tensor Ayy and Axx analyzing powers in deuteronproton elastic scattering obtained at Nuclotron in the energy range 400-1800 MeV are presented. These data have been obtained in 2016-2017 at DSS setup at internal target station using polarized deuteron beam from new source of polarized ions. The preliminary data on the deuteron analyzing powers in in the wide energy range demonstrate the sensitivity to the shortrange spin structure of the nucleon-nucleon correlation
Dp breakup reaction investigation using polarized and unpolarized deuteron beam
Deuteron Spin Structure (DSS) collaboration program is aimed on few nucleon correlations investigation using unpolarized and polarized deuteron beam at intermediate energy range. Data of the dp breakup reaction have been obtained at energy range from 300 - 500 MeV of deuteron energy for various detector configurations in region where few nucleon correlations and relativistic effects can play significant rol
Measurement of the tensor Ayy and vector Ay analyzing powers of the deuteron inelastic scattering off berillium at 5.0 GeV/c and 178 mr
Tensor Ayy and vector Ay analyzing powers in the inelastic scattering of
deuterons with the momentum of 5.0 GeV/c on beryllium at an angle of 178 mr in
the vicinity of the excitation of baryonic resonances with masses up to
1.8 GeV/c^2 have been measured. The Ayy data are in a good agreement with the
previous data obtained at 4.5 and 5.5 GeV/c. The results of the experiment are
compared with the predictions of the plane wave impulse approximation and
\omega-meson exchange models.Comment: 18 pages, 9 figure
First results on the measurements of the proton beam polarization at internal target at Nuclotron
The spin program at NICA using SPD and MPD requires high intensity polarized proton beam with high value of the beam polarization. First results on the measurements of the proton beam polarization performed at internal target at Nuclotron are reported. The polarization of the proton beam provided by new source of polarized ions has been measured at 500 MeV using quasielastic proton-proton scattering and DSS setup at internal targe
Tensor Ayy and vector Ay analyzing powers in the H(d,d')X and ^{12}C(d,d')X reactons at initial deuteron momenta of 9 GeV/c in the region of baryonic resonances excitation
The angular dependence of the tensor Ayy and vector Ay analyzing powers in
the inelastic scattering of deuterons with a momentum of 9.0 GeV/c on hydrogen
and carbon have been measured. The range of measurements corresponds to the
baryonic resonance excitation with masses 2.2--2.6 GeV/c^2. The Ayy data being
in good agreement with the previous results demonstrate an approximate
scaling up to -1.5 (GeV/c)^2. The large values of A_y show a significant role
of the spin-dependent part of the elementary amplitude of the NN->NN* reaction.
The results of the experiment are compared with model predictions of the
plane-wave impulse approximation.Comment: 7 pages, 7 figures. submitted to Yad.Fi
