0099452HaldersonThis proposal has projects in two areas of nuclear theory. The first project will use the recoil-corrected continuum shell model (RSCCM) to investigate nucleon induced reactions on light nuclei, in particular those nucleon capture reactions of astrophysical interest. The recent extension of this model to p-shell nuclei allows the study of single neutron halo nuclei, polarized electron scattering data, and a variety of other topics including the effective interaction of nuclear structure theory. The second area of research is in the study of the hyperon-nucleon interaction with meager experimental input from scattering and binding energy systematics of light hypernuclei. The RCCSM, by allowing the hyperon to be bound or unbound, is particularly suitable for hypernuclear structure calculations because bound state excitation and quasi-free scattering are included in one consistent framework. The theoretical understanding expected from this work would be useful for experiments both at Brookhaven and Jefferson Lab.

0099452 Halderson这个提议在核理论的两个领域有项目。 第一个项目将使用反冲修正的连续壳模型（RSCCM）来研究轻核上的核子诱导反应，特别是具有天体物理意义的核子俘获反应。 最近将该模型扩展到p壳层核，可以研究单个中子晕核、极化电子散射数据以及包括核结构理论的有效相互作用在内的各种其他主题。 第二个研究领域是在来自轻超核的散射和结合能系统学的少量实验输入下研究超子-核子相互作用。 RCCSM允许超子被束缚或不被束缚，特别适合于超核结构的计算，因为束缚态激发和准自由散射被包含在一个一致的框架中。 预期从这项工作的理论理解将是有用的实验都在布鲁克海文和杰斐逊实验室。
