Beam polarization measurement in scattering experiments with a high accuracy and the lowest possible cost is an important issue. In this regard, deuteron beam polarization was measured in the low-energy beam line easily with a relatively low cost procedure and in a very short time by Lamb Shift Polarimeter (LSP). Also, the beam polarization has been measured in high-energy beam line with BINA. In low-energy line, a polarized beam of deuterons delivered by POLIS was decelerated and focused on LSP detection system. Three resonances between 52mT and 63mT show the distribution of different spin states of polarized deuteron beam. In high-energy beam line, polarization can be measured employing BINA via the H(d,d)p reaction. The asymmetry ratio, was obtained as a function of azimuthal angle, φ, for several polar scattering angles. Knowing values of the analyzing powers, the ratio has been used to extract the polarization results. The obtained results show that polarization of deuteron beam that is accelerated up to the energy of 130 MeV is almost the same before and after acceleration

Information obtained from nucleus as a bound system of nucleons and from nucleon-nucleon scattering experiments is a strong tool for studying various aspects of nuclear forces. Deuteron-deuteron scattering as a four-nucleon system can provide useful information. So, scattering experiment of a polarized beam of deuteron with kinetic energy of65 MeV/nucleon from a liquid-deuterium target was done at Kernfysisch Versneller Instituut (KVI) and the Big Instrument for Nuclear-polarization Analysis (BINA) was utilized. The obtained data from this experiment were analyzed and presented in this paper. Some results for vector and tensor analyzing powers for a part of the phase space of the Three-Body Break-up channel in d-d scattering are discussed herein. This dataset will be used to test the upcoming theoretical calculations for a four nucleon system, especially for studying the three-nucleon force effects.

The reaction γ + {pp}s → p + p, where diproton {pp}s is a proton pair in 1S0 state, is a spin-isospin partner of the fundamental reaction of deuteron photodisintegration. The inverse reaction, the hard bremsstrahlung p + p → γ + {pp}s, has been observed with the ANKE spectometer at COSY-Jülich. In addition to differential cross section measured earlier, in this work it's analyzing power has been measured at forward angles at several energies in the region of Δ(1232) isobar exictation.

The model of microscopic optical potential based on calculations of the one-particle Green function mass operator using the effective Skyrme nucleon-nucleon forces has been applied for describing cross sections and analyzing powers of the elastic nucleon-nucleus scattering. The Skyrme force parameters have been optimized by fitting a chosen angular distribution of the elastic neutron-nucleus scattering with simultaneous control of main characteristics of the nuclear matter and the binding energy and rms charge radius of the target nucleus. The found Skyrme forces have been used to analyze differential cross sections and analyzing powers of elastic neutron scattering by nuclei in a wide range of mass numbers. The calculations have given a satisfactory description of experimental data on elastic neutron-nucleus scattering and reasonable values of the main parameters for the symmetric nuclear matter and even-even nuclei. Analogous calculations have been performed for describing experimental data on the elastic proton-nucleus scattering, which have yielded encouraging results.

The spin transfer from vertically polarized beam protons to Λ or Σ hyperons of the associated strangeness production p → p → pK + Λ and p → p → pK 0 Σ + is described with the depolarization coefficient D NN . As the polarization of the hyperons is determined by their weak decays, detectors, which have a large acceptance for the decay particles, are needed. In this paper a formula is derived, which describes the depolarization coefficient D NN by count rates of a 4π detector. It is shown that formulas, which are given in publications for detectors with restricted acceptance, are specific cases of this formula for a 4π detector. [ABSTRACT FROM AUTHOR]
