9600417 Rapaport This Americas Program award will support a collaborative research project between Dr. Jacobo Rapaport, Ohio University, and Dr. Francisco Brieva, Universidad de Chile. The researchers intend to address basic issues related to the understanding of the reaction and excitation mechanisms in nucleon induced inclusive reactions. The purpose of the planned experiments is to provide high quality data on spin transfer for subsequent theoretical interpretation and analysis. The objectives are to develop a theoretical framework to interpret the data in terms of couplings between reaction and excitation mechanisms and to study the dependence on the nucleon-nucleon interaction. The experiment might eventually lead to a much more fundamental understanding of nuclear phenomena in terms of a microscopic theory. The microscopic understanding of simple nuclear phenomena relating to the structure and reaction degrees of freedom has been greatly enhanced in the last few years both from the experimental and theoretical approaches. However, there still exist important and troubling questions about how a nucleus responds to certain classes of external stimuli. The proposed experiments, to take place at the Indiana University Cyclotron Facility, should provide a complete set of data to test more deeply the different theoretical models. The group of the University of Chile will develop new theoretical calculations to explain the data by working on the development of a microscopic theory for reactions. They will then construct the codes for calculating the corresponding observables. The results of this collaborative effort could be a major contribution to the field of charge exchange in nuclear reactions. ***

小行星9600417 该美洲计划奖将支持俄亥俄州大学Jacobo Rapaport博士和智利大学弗朗西斯科Brieva博士之间的合作研究项目。 研究人员打算解决与理解核子诱导包容性反应中的反应和激发机制有关的基本问题。计划实验的目的是为后续的理论解释和分析提供有关自旋转移的高质量数据。 其目标是建立一个理论框架来解释反应和激发机制之间的耦合数据，并研究对核子-核子相互作用的依赖性。 这个实验可能最终导致从微观理论的角度对核现象有更基本的理解。 在过去的几年里，无论是从实验还是从理论上，对与结构和反应自由度有关的简单核现象的微观理解都得到了极大的加强。 然而，关于细胞核如何对某些类型的外部刺激做出反应，仍然存在一些重要而令人不安的问题。 拟议中的实验将在印第安纳州大学的回旋加速器设施进行，它将提供一套完整的数据，以更深入地检验不同的理论模型。 智利大学的研究小组将开发新的理论计算，通过发展反应的微观理论来解释这些数据。然后，他们将构造用于计算相应的可观测量的代码。 这一合作努力的结果可能是对核反应中电荷交换领域的重大贡献。 ***
