项目摘要

The purpose of this category was the mainly planning and managing for the dispatch of researcher to England to push forward the second UK-Japan Neutron Scattering Research Collaboration Program (hereinafter called UK Japan Collaboration Program). The budget of this program was applied to the particular field of research (1): The study of local spin-atomic structure and its dynamics (1999fy-2003fy, Representative : Masatoshi Arai, Subject No.11211101). UK-Japan Collaboration Program is to perform the neutron scattering experiment using the most intense (now in the world) pulsed neutron source in the ISIS facility of Rutherford Appleton Research Laboratory in England. The neutron intensity of ISIS is about 50 times high to the neutron source of KENS (Neutron Science Laboratory, Institute of Materials Structure Science, High Energy Accelerator Research Organization) in Japan. This program has created the excellent research results by highly accurate neutron scattering experiments which are impossible to do domestically and at the same time, it has supported the progress of research in KENS. This study group have supported the design, construction and installation of MARS spectrometer in ISIS and after start of its normal operation, it will be served as a main instrument in this Collaboration Program and for the measuring region uncovered by MARS, other existent instruments in ISIS can also be utilized. In accordance with this fundamental study program, Japanese researchers have been dispatched to England to clarify the functions and properties of the material on the microscopic viewpoint. This task has been performed by the appropriate measurement in the neutron scattering experiment for the dynamical structure factor which is widely distributed in the energy-momentum space. Under this program 58 experiments have been carried out and 45 research papers have been published.

这一类别的目的主要是计划和管理派遣研究人员到英国推进第二次英日中子散射研究合作计划(以下简称英日合作计划)。该方案的预算用于特定的研究领域(1)：局域自旋原子结构及其动力学的研究(1999 FY-2003 FY，代表：荒井雅敏，课题号11211101)。英国-日本合作计划将在英国卢瑟福·阿普尔顿研究实验室的ISIS设施中使用目前世界上最强的脉冲中子源进行中子散射实验。ISIS的中子强度大约是日本KENS(高能加速器研究组织材料结构科学研究所中子科学实验室)中子源的50倍。该计划通过高精度的中子散射实验创造了国内无法完成的优秀研究成果，同时也支持了KENS的研究进展。该研究小组支持了ISIS火星光谱仪的设计、建造和安装，在其正常运行后，它将作为本次合作计划的主要仪器，对于MARS发现的测量区域，也可以使用ISIS现有的其他仪器。根据这一基础研究计划，日本研究人员已被派往英国，从微观角度阐明材料的功能和性质。这项任务是通过在中子散射实验中对能量-动量空间中广泛分布的动力结构因子进行适当的测量来完成的。在该计划下，开展了58项实验，发表了45篇研究论文。
