摘要:

在日本理研加速器研究所和日本原子核物理研究所的VBLHEP(JINR)上,用极化和非极化的氘核束对d,3 H和3 He的自旋结构进行了研究。本文介绍了dp弹性散射、d(d,~ 3 H)p和d(d,~ 3 He)n反应中分析本领的实验研究结果。在核加速器(VBLHEP)上获得了880和2000 MeV的dp弹性散射的矢量和张量分析功率。对2000 MeV氘的分析本领Ay、Ayy的计算结果与相对论多重散射模型的计算结果进行了比较。在Ed = 200和270 MeV下得到的d(d,3 H)p和d(d,3 He)n反应的张量分析能力的数据表明了对3 H,3 He和氘核自旋结构的敏感性。在单核子交换模型框架内,实验结果与理论计算之间存在着本质的分歧。本文讨论了在Nuclotron上用内束和引出束研究dp弹性散射、dp非介子分裂、d(d,3 He)n、d(d,3 H)p和d(3 He,4 He)p反应中极化效应的广泛实验计划。

英文摘要:

The investigation of the d, 3H and 3He spin structure has been performed at the RIKEN(Japan) accelerator research facility and VBLHEP(JINR) using both polarized and unpolarized deuteron beams. The experimental results on the analyzing powers studies in dp- elastic scattering, d(d,3H)p and d(d,3He)n reactions are presented. The vector and tensor analyzing powers for dp-elastic scattering at 880 and 2000 MeV are obtained at the Nuclotron(VBLHEP). The result on the analyzing powers Ay, Ayy of the deuteron at 2000 MeV are compared with relativistic multiple scattering model calculations. The data on the tensor analyzing powers for the d(d,3H)p and d(d,3He)n reactions obtained at Ed = 200 and 270 MeV demonstrate the sensitivity to the 3H, 3He and deuteron spin structure. The essential disagreements between the experimental results and the theoretical calculations within the one-nucleon exchange model framework are observed. The wide experimental program on the study of the polarization effects in dp- elastic scattering, dp-nonmesonic breakup, d(d,3He)n, d(d,3H)p and d(3He,4He)p reactions using internal and extracted beam at Nuclotron is discussed.
