Electromagnetic Interaction Studies of Nucleons and Nuclei

研究将利用电磁和电弱相互作用来研究核子和原子核。主要重点是测量基本核子形状因子，研究以氘核为重点的少体系统，并启动宇称违反不对称测量程序，以确定奇异夸克混合物对核子基态的作用。这项研究在贝茨直线加速器中心和CEBAF进行，质子和中子偏振计的校准在IUCF和Saclay进行。支持的工作包括：(1)贝茨反冲质子偏振计的调试，并使用该偏振计进行初步实验计划；(2)继续在贝茨和CEBAF进行中子电和磁形状因子测量；(3)开展d(e,e'p)n极化传递测量计划，作为CEBAF初始a厅物理计划的一部分；(4)开始在CEBAF进行宇称破坏测量的实验计划。开发和利用新的自旋物理技术是本项目的主要目标。威廉玛丽学院也将使用CEBAF的设备资金和研究生人力来设计和建造这个巧合触发的大厅。

Research will be carried out utilizing electromagnetic and electroweak interactions to study nucleons and nuclei. Primary emphasis is on measuring elementary nucleon form factors, studying the few-body system with emphasis on the deuteron, and initiating a program of parity violating asymmetry measurements to determine the role of strange quark admixtures to the nucleon ground state. This research is being undertaken at the Bates Linear Accelerator Center and CEBAF, with calibration of proton and neutron polarimeters being performed at IUCF and Saclay. Efforts to be supported include: (1) commissioning of the Bates recoil proton polarimeter and carrying out an initial experimental program with this polarimeter; (2) continuation of neutron electric and magnetic form factor measurements at Bates and CEBAF; (3) carrying out a program of d(e,e'p)n polarization transfer measurements as part of the initial Hall A physics program at CEBAF; (4) beginning an experimental program of parity violation measurements at CEBAF. The development and exploitation of new spin physics techniques are major objectives of this program. William and Mary College will also design and construct the Hall A coincidence trigger using CEBAF equipment funds and graduate student manpower.
