Research in Intermediate Energy Nuclear Physics

拟议中的研究旨在回答有关核子和核少体系统结构的基本问题。实验是在中等能量的电子加速器上进行的。在过去的二十年中，在产生极化的，连续的电子束和极化的内部气体目标的出现方面的发展已经引入了一种新的测量技术，充分利用自旋自由度。这项新技术打开了一扇窗户，可以对中子的电荷分布等基本量进行明确的测量。精确了解中能中子的结构，对于基于强相互作用的基本理论量子色动力学约束核子结构模型是必不可少的。它也是理解少体系统的核物理以及其他基本电子散射实验结果的关键因素。拟议的活动将产生新的科学家在博士学位。该项目将培养博士后一级的年轻科学家，将为本科生提供基础物理学的研究经验，并将有助于一所大型州立大学成为一流的研究机构。提高妇女和少数民族的职业地位是这一进程的一个组成部分。此外，对最先进设备的需求利用了大学的技术劳动力和整个社会。

The proposed research seeks to answer fundamental questions about the structure of the nucleon and of the nuclear few-body systems. Experiments are carried out at electron accelerators of intermediate energies. Developments in the last two decades in terms of producing polarized, continuous electron beams and the advent of polarized internal gas targets have introduced a new technique of measurements that fully exploit the spin degrees of freedom. This new technique opens the window to perform definite measurements of fundamental quantities like the charge distribution of the neutron. Precise knowledge of the structure of the neutron at intermediate energies is essential to constrain models of nucleon structure based on the fundamental theory of the strong interaction, quantum chromodynamics. It is also a key ingredient in understanding the nuclear physics of the few-body systems as well as the results derived from other fundamental electron scattering experiments. The proposed activities will produce new scientists at the Ph.D. level, will train young scientists at the postdoctoral level, will give research experience in fundamental physics to undergraduate students, and will contribute to the ascent of a large state university as a premier research institution. The advancement of the careers of women and ethnic minorities is an integral part of this process. Furthermore, the demand for state-of-the-art equipment utilizes the University's technical workforce and that of the society at large.
