9401924 Fletcher This Americas Program award will support Dr. Neil Fletcher, of Florida State University, Tallahassee, in a research collaboration in nuclear physics with Dr. Jacinto Liendo, Instituto Venezolano de Investigaciones Cientificas, Caracas. The main objective of the project will be to measure the alpha- particle widths of several states near breakup threshold in 13C, with the goal of further understanding the cluster structure properties of the states and improving the obtainable energy resolution. In this, they will have access to a new high- resolution nuclear spectroscopic tool developed by the two researchers. The original detection method for low energy nuclear physics, resonant particle decay spectroscopy, has not been utilized for ultra-high energy resolution in nuclear reactions. One of the primary aspects of this research will be to apply this method, and the researchers' newly discovered angular correlation property, to problems in the structure of states in p-shell nuclei. The results will be of high interest, both for the specific information obtained and as a demonstration of a potential new tool in nuclear astrophysics. ***

小弗莱彻9401924 该美洲计划奖将支持塔拉哈西佛罗里达州立大学的Neil弗莱彻博士与加拉加斯委内瑞拉科学研究所的Jacinto Liendo博士进行核物理研究合作。 该项目的主要目标是测量13 C中接近破裂阈值的几个态的α粒子宽度，目的是进一步了解这些态的团簇结构特性，并提高可获得的能量分辨率。 在这方面，他们将有机会使用这两位研究人员开发的一种新的高分辨率核光谱工具。 低能核物理的原始探测方法，共振粒子衰变谱，尚未用于核反应中的超高能量分辨率。 这项研究的主要方面之一将是将这种方法和研究人员新发现的角相关性质应用于p壳层核的态结构问题。 其结果将具有很高的意义，既可提供所获得的具体信息，也可作为核天体物理学中一种潜在的新工具的展示。 ***
