*** 9732634 Halderson Projects are proposed in two areas of nuclear theory. The first area concerns the interaction of nuclei with medium energy electrons, mesons, and nucleons. This investigation provides information on the interaction mechanism between these probes and the constituent nucleons, the behavior and decay processes of nuclei at high excitation energy, and the distribution of nucleons within nuclei. The second area of research 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 strange or charmed baryons with nucleons and with each other. These investigations will provide basic information on the strong interaction at low energies. In addition, an understanding of these interactions will provide predictions on the existence of exotic nuclei with few or no protons and the strangeness content of neutron stars. ***

** 9732634在核理论的两个领域提出了Halderson项目。第一个领域涉及原子核与中能电子、介子和核子的相互作用。本研究提供了这些探针与组成核子的相互作用机制、核子在高激发能下的行为和衰变过程以及核子在核子内的分布等方面的信息。第二个研究领域是超核物理学。超核至少包含一个奇异度或粲子非零的重子。虽然它们的寿命很短，但超核为确定奇异重子或迷人重子与核子以及彼此之间的相互作用提供了一个实验室。这些研究将提供低能强相互作用的基本信息。此外，对这些相互作用的理解将有助于预测质子很少或没有质子的奇异核的存在以及中子星的奇异成分。＊＊＊
