U.S.-Venezuela: High Resolution Observation of Particle Decaying Excited States of P-Shell Nuclei

9401924弗莱彻这一美洲项目奖将支持塔拉哈西佛罗里达州立大学的尼尔·弗莱彻博士与加拉加斯威尼佐拉诺科学研究所的哈辛托·利恩多博士在核物理方面的研究合作。该项目的主要目标将是测量13C分裂阈值附近几个态的α粒子宽度，目的是进一步了解这些态的团簇结构性质，并提高可获得的能量分辨率。在这一过程中，他们将获得两位研究人员开发的一种新的高分辨率核光谱工具。原来的低能核物理探测方法--共振粒子衰变光谱，在核反应中的超高能量分辨率方面还没有得到应用。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关联性质应用于p壳层核态结构的问题。这些结果将引起人们的极大兴趣，既是因为所获得的具体信息，也是作为核天体物理学中潜在的新工具的示范。***

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. ***
