Spin Physics in Nuclei and Nucleons (SPINN)

将在IUCF、LAMPF、BNL和Nikhef开展中能核物理研究，重点是核结构和确定有效核子-核子相互作用。极化转移反应将被用来探索相互作用的张量、中心和自旋轨道分量。用不同的探测器进行测量，再加上对核态的仔细选择，例如具有最大角动量转移的拉伸态跃迁，将被用来获得不同成分的更精细的视图。壳层模型占据数、径向轨道形状、核心极化、介子交换电流和相对论效应等信息也将从这项工作中获得。BNL将利用线偏振伽马射线对少数几个天体系统的结构进行多核子敲除实验。将对后一项工作的电子散射扩展的实验进行规划。

Research in intermediate energy nuclear physics will be carried out at IUCF, LAMPF, BNL, and NIKHEF, focussing on nuclear structure and determination of the effective nucleon- nucleon interaction. Polarization transfer reactions will be used to explore the tensor, central, and spin-orbits components of the interaction. Measurements with different probes, together with a careful choice of nuclear states, such as the stretch states transitions with maximal angular momentum transfer, will be used to obtain a much refined view of the different components. Information on shell model occupation numbers, shapes of radial orbitals, core polarization, meson exchange currents, and relativistic effects will also be obtained from this work. Multi-nucleon knockout experiments on the structure of few body systems will be carried out at BNL using linearly polarized gamma rays. Planning of experiments for electron scattering extensions of this latter work will be carried out.
