Investigations in the Microscopic Theory of Nuclear Structure and Reactions

这些项目是在核理论的两个领域提出的。第一个领域涉及发射组成核子的阈值以上的核的结构。这一能区的核模型的发展提供了一种分析和关联来自核子散射实验和实验的数据的手段，在这些实验中，核子被各种探测器(如电子和介子)从原子核中击倒。这些研究提供了关于高激发时原子核的结构和核子在原子核内的分布的信息。第二个领域是超核物理。超核包含至少一个具有非零奇异性或魅力的重子。虽然它们的寿命很短，但超核为确定奇异重子与核子以及它们之间的相互作用提供了一个实验室。它们也为研究奇异重子的特定衰变模式提供了唯一实用的手段。与自由奇异重子的衰变不同，这种衰变模式不会产生介子。提出了确定这些奇异重子相互作用和非介子衰变机制的研究。

Projects are proposed in two areas of nuclear theory. The first area concerns the structure of nuclei above the threshold for emitting constituent nucleons. Development of nuclear models for this energy region provide a means of analyzing and correlating data from nucleon scattering experiments and experiments in which a nucleon is knocked out from a nucleus by a variety of probes, such a electrons and mesons. These investigations provide information on the structure of nuclei at high excitation and the distribution of nucleons within nuclei. The second area is hypernuclear physics. Hypernuclei contain at least one baryon with non-zero strangeness or charm. Although their lifetimes are very short, hypernuclei provide a laboratory for determining the interaction of exotic baryons with nucleons and with each other. They also provide the only practical means for studying a particular decay mode for the strange baryons. This decay mode, unlike the decay of a free strange baryon, is one in which no mesons are produced. Investigations are proposed for both determining the interactions of these exotic baryons and the mechanism for non-mesonic decay.
