Research will be carried out in the study of high energy nucleons and pairs following muon capture by nuclei. The underlying physics motivation is to probe to high momentum structure of the nuclear wave function and explore the meson exchange process. The isospin structure of giant resonances will also be studied using pion single charge exchange reactions, both inclusive and in coincidence with subsequent decay particles. The angular momentum and isospion structure of giant resonances will be studied by inelastic electron excitation, both inclusive and in coincidence with subsequent decay particles. As soon as polarized electrons become available at Bates they will be used to provide an additional degree of freedom in the study. These two latter studies are motivated out of interest in many-body nuclear structure.

研究将在高能核子和高能核对被原子核捕获后进行。其背后的物理动机是探索核波函数的高动量结构和探索介子交换过程。还将利用包括和符合后续衰变粒子的π单电荷交换反应来研究巨共振的同位旋结构。巨共振的角动量和同位旋结构将通过非弹性电子激发来研究，包括和符合随后的衰变粒子。一旦极化电子在贝茨获得，它们将被用来在研究中提供额外的自由度。后两项研究是出于对多体核结构的兴趣。
