Experimental Nuclear Physics Research Program

这项拨款支持在美国、加拿大和欧洲使用各种加速器研究中、高能核反应。这些研究考察了核反应的动力学和描述核国家结构所需的自由度。工作内容包括原子核对飞行中的介子的真实吸收，包括多核子吸收，以及量化有效核子-核子相互作用的非弹性散射分析及其在核结构研究中的应用。新的中能质子实验将集中在轻元素产生介子和等压线上。研究还将利用高能的电磁相互作用，集中研究原子核的夸克自由度。更常规的原子核结构测量和根据核子自由度研究反应动力学也在计划之中。将进行设计和开发工作，为CEBAF和PEGASYS的新项目做准备。

This grant supports research using a variety of accelerators in the U.S., Canada, and Europe to study intermediate and high energy nuclear reactions. These studies examine both the dynamics of nuclear reactions and the degrees of freedom required to describe the structure of nuclear states. The work includes research on true absorption of in- flight pions by nuclei, including multi-nucleon absorption, as well as analyses of inelastic scattering to quantify the effective nucleon-nucleon interaction and its use in studying nuclear structure. New experiments with medium energy protons will focus on -meson and -isobar production from light elements. Research will also be conducted using electromagnetic interactions at higher energies focusing on the quark degrees of freedom of nuclei. More conventional measurements of the structure of nuclei and studies of reaction dynamics in terms of nucleonic degrees of freedom are also planned. Design and development efforts will be conducted in preparation for new projects at CEBAF and PEGASYS.
