9908727TsangThis US-Brazil award will provide support for Drs. Man-Yee B. Tsang and William G. Lynch of the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University to collaborate with colleagues at Brazil's Federal University of Rio de Janeiro, led by Dr. Raul Donangelo. Their goal is to study the theoretical interpretation of nuclear multifragmentation, a process that may provide insight into the liquid-gas phase transition of nuclear matter.This collaboration will bring experimentalists from Michigan State to work with theoreticians from the Federal University of Rio de Janeiro. Dr. Donangelo is one of the original developers of the widely used Statistical Multifragmentation Model (SMM). The group at NSCL possesses a unique set of multifragmentation data that requires significant improvements to the SMM and other models for its interpretation. So far, the two groups have focussed on these improvements, which could make the model capable of accurate statistical predictions of isotopic yields. When the groups meet at NSCL, they will work on comparisons to the large volume of data they have accumulated, while in Rio the emphasis will be on model developments.***

9908727 Tsang这个美国-巴西奖项将为密歇根州立大学国家超导回旋实验室(NSCL)的万义B.曾文仪博士和William G.Lynch博士提供支持，与由Raul Donangelo博士领导的巴西里约热内卢联邦大学的同事合作。他们的目标是研究核多重碎裂的理论解释，这一过程可能会为了解核物质的液-气相变提供洞察。这一合作将带来来自密歇根州立大学的实验者与里约热内卢联邦大学的理论家合作。多南杰洛博士是广泛使用的统计多重碎片化模型(SMM)的最初开发者之一。NSCL的小组拥有一组独特的多碎片数据，需要对SMM和其他模型进行重大改进才能进行解释。到目前为止，这两个小组一直专注于这些改进，这可能使该模型能够准确地对同位素产量进行统计预测。当这些小组在NSCL开会时，他们将与他们积累的大量数据进行比较，而在里约热内卢，重点将是模型开发。
