Radiative Capture Studies at Intermediate Energies

用户模式研究计划将在 基本的辐射俘获反应。 实验 研究将在加拿大的TRIUMF进行，包括 π介子在极化质子上的辐射俘获，在KEK， 涉及高能辐射中子-质子俘获。 π介子的工作将增进我们对π介子的理解 生产横截面，并阐明了基础 夸克子结构和核子中的相互作用。 的 中子-质子捕获工作将提供新的数据寻址 用夸克描述np系统 或介子-核子自由度。 模拟，数据 分析、解释和其他相关活动将 是在肯塔基州大学进行的。

A user mode research program will be carried out in fundamental radiative capture reactions. The experimental studies will be conducted at TRIUMF in Canada, involving radiative capture of pions on polarized protons, and at KEK, involving radiative neutron-proton capture at high energies. The pion work will improve our understanding of the photopion production cross section and shed light on the underlying quark sub-structure and interactions in nucleons. The neutron-proton capture work will provide new data addressing alternative descriptions of the np system in terms of quarks or meson-nucleon degrees of freedom. Simulations, data analysis, interpretation, and other related activities will be carried out at the University of Kentucky.
