9804307 WeppnerThis project involves a study of exotic neutron rich nuclei, specifically the neutron `halo' nuclei helium 6 and helium 8. The availability of a consistent theoretical formulation of proton-nucleus scattering theory with the ability to perform these rigorous calculations provides a powerful tool to explain the properties of exotic nuclei. Motivation for this project comes from recent experiments at radioactive nuclear beam facilities as well as theoretical work recently done by a group in Surrey. The project is designed to be carried out during the summer of 1998. The goal is to perform elastic scattering calculations on exotic helium in an intermediate energy range to examine the behavior of elastic scattering observables as functions of different spatial extensions of the neutron `halo'. This will be done following two different courses. One will be to use recent realistic structure models from the literature. The other will be to use the description of the nucleus by a simpler model, namely harmonic oscillator wave-functions. This research requires the purchase of a state of the art visualization tool for the undergraduate institution. This software acquisition will also strengthen the college's Advanced Scientific Computing Laboratory used by all the disciplines in the natural arts and sciences.

9804307 Weppner该项目涉及对奇异富中子核的研究，特别是中子“晕”核氦6和氦8。 质子-核散射理论的一致性理论公式的可用性与执行这些严格计算的能力提供了一个强大的工具来解释奇异核的性质。这个项目的动机来自于最近在放射性核束设施的实验以及萨里的一个小组最近所做的理论工作。该项目计划在1998年夏季执行。 目标是在中间能量范围内对外来氦进行弹性散射计算，以研究弹性散射观测值作为中子“晕”不同空间扩展的函数的行为。这将在两个不同的课程之后完成。 一个将是使用最近的现实结构模型的文献。另一种方法是用一个更简单的模型来描述原子核，即谐振子波函数。这项研究需要购买一个国家的最先进的可视化工具的本科院校。此次软件收购还将加强学院的高级科学计算实验室，用于自然艺术和科学的所有学科。
