AbstractAbstract
[en] Neutron-proton total cross section differences ΔσT and ΔσL as well as elastic scattering observables (including the differential cross sections), measured at SATURNE II, are presented. A major part of results was measured using the quasimonoenergetic polarized neutron beam and/or the polarized proton target. At several energies data are compared with measurements obtained in other laboratories. First direct reconstructions of the np scattering matrix at 0.84 and 0.88 GeV are shown. (author)

AbstractAbstract
[en] The present review is devoted to the spin-dependent experiments prepared at the JINR Veksler-Baldin Laboratory of High Energies and carried out at the Synchrophasotron or Nuclotron accelerators. The acceleration of polarized deuterons, experiments using the internal targets, the beam extraction and the polarimetry are briefly described. Then, representative experiments using either the extracted deuteron beam or secondary beams of polarized nucleons produced by polarized deuterons, are considered. Three current experiments: DELTA-SIGMA, DELTA, pp SINGLET, and recently BES, require the polarized nucleon beams in conjunction with the Dubna polarized proton target. Already available ΔσL(np) results from the first experiment show an unexpected energy dependence. The experiment DELTA should investigate the nucleon strangeness. The aim of the pp SINGLET is to study a possible resonant behavior of the spin-singlet pp-scattering amplitude. BES proposes the measurement of the complete experiment in dp backward elastic scattering. For all other Dubna experiments, unpolarized nucleon or nuclei targets are used. The polarized deuteron beam allows one to determine spin-dependent observables necessary for understanding the deuteron structure, as well as the nucleon substructure. One part of investigations concerns deuteron break-up reactions and deuteron-proton backward elastic scattering. A considerable amount of data was obtained in this domain. Another part is dedicated to the measurements of the same spin-dependent observables in a cumulativeregion. Interesting results were obtained for proton or pion productions in inclusive and semi-inclusive measurements

Настоящий обзор посвящен экспериментам с поляризованными пучками, которые были подготовлены в ЛВЭ ОИЯИ и выполнены на синхрофазотроне и нуклотроне. Коротко описаны ускорение поляризованных дейтронов, эксперименты на внутренних мишенях, вывод пучка и поляриметрия. Также описаны основные эксперименты на выведенных пучках дейтронов и на вторичных пучках поляризованных нуклонов. В трех текущих экспериментах - Дельта-Сигма, Дельта и pp-Singlet - используются поляризованные нуклонные пучки вместе с дубненской поляризованной протонной мишенью. Результаты, полученные уже в первом эксперименте по измерению ΔσL(np), показали неожиданную зависимость данных от энергии. Эксперимент Дельта направлен на изучение странности нуклона. Целью третьего эксперимента является проверка возможного резонансного поведения спин-синглетной амплитуды рр-рассеяния. Все другие дубненские эксперименты используют неполяризованные мишени нуклонов или ядер. Поляризованный дейтронный пучок позволил определить зависимые от спина величины, необходимые для изучения структуры дейтрона и нуклонной субструктуры. В одних экспериментах измеряются две зависимые от спина величины: в реакциях с развалом дейтрона и в дейтрон-протонном упругом рассеянии назад. Большое количество данных было получено в этой области. В других экспериментах измеряются те же самые наблюдаемые в кумулятивной области. Интересные результаты получены для рождения протонов и пионов в инклюзивных измерениях. Анализирующая способность измерялась в неупругих (d, d)-реакциях в области роперовских резонансовPrimary Subject

AbstractAbstract
[en] Using a proton polarized beam from SATURNE II and the Saclay frozen spin target the spin correlation parameter A/sub oonn/ and the total cross section difference Δsigma/sub T/ were measured. Including these preliminary data a phase shift analysis has been made. A possible structure in the pp spin singlet state near the mass 2.22 GeV is observed. 7 references, 8 figures

AbstractAbstract
[en] The uniqueness of the direct reconstruction of pp elastic scattering amplitudes from the observables measured in the Nucleon-Nucleon experimental program at SATURNE 2 is discussed. The amplitudes were deduced analytically solving bilinear relations expressing the observables in terms of invariant amplitudes. It is shown that the choice of observables in the experimental program allows, in principle, a complete and unique analytical reconstruction at all energies involved if experimental errors are ignored. This is shown to apply to two different sets of 11 observables and to a set of 10 observables. 18 refs

AbstractAbstract
[en] The present review is devoted to the spin-dependent experiments carried out or prepared at the JINR LHE Synchrocyclotron. The acceleration of polarized deuterons, and experiments using the internal targets, the beam extraction and the polarimetry are briefly described. Then, representative experiments using either the extracted deuteron beam or secondary beams of polarized nucleons produced by polarized deuterons are treated. Three current experiments: 'DELTA-SIGMA', 'DELTA' and 'pp-SINGLET', require the polarized nucleon beams in conjunction with the Dubna polarized proton target. Already available ΔσL(np) results from the first experiment show unexpected energy dependence. Experiment 'DELTA' should investigate the nucleon strangeness. The aim of the third experiment is to study a possible resonant behavior of the spin-singlet pp scattering amplitude. For all other Dubna experiments unpolarized nucleon or nuclei targets are used. The polarized deuteron beam allows determining spin-dependent observable necessary for understanding the deuteron structure, as well as the nucleon substructure. One part of investigations concerns deuteron break-up reactions and deuteron proton backward elastic scattering. A considerable amount of data was obtained in this domain. Another part is dedicated to the measurements of the same spin-dependent observable in a 'cumulative' region. Interesting results were obtained for proton or pion productions in inclusive and semi-inclusive measurements. In the field of inelastic deuteron reactions, the analyzing power measurements were performed in the region covering Roper resonances. Many existing models are in disagreement with observed momentum dependences of different results. Finally, the proton-carbon analyzing power measurements extended the momentum region of rescattering observables. Some inclusive Dubna results are compared to exclusive Saclay data, and to lepton-deuteron measurements. Most of the JINR LHE experiments are carried out within the framework of a large international collaboration
