U.S.-Russia Collaborative Research: Isospin Dependence of Fragmentation and Spallation Reactions

这是一个美俄合作研究项目，将探索在1 GeV质子诱导反应中产生的碎片和散裂反应的同位旋依赖性。首席研究员为密西根州立大学ManYee B. Tsang博士。她的俄罗斯合作者是圣彼得堡核物理研究所的柳德米拉·安德罗年科博士和米哈伊尔·安德罗年科博士。这个项目将利用两个研究小组的独特能力。美国小组率先进行了等尺度分析和建模，而俄罗斯小组在过去几十年中积累了许多不同同位素目标的1 GeV质子诱导碎裂和散裂数据。这次合作将进一步理解等尺度现象的全局性质，并可能提取核状态方程中的对称项。这个核物理研究项目实现了将美国和中欧/东欧的顶尖专家聚集在一起的计划目标，在平等、互惠和互利的基础上，在共同感兴趣和能力强的领域结合互补的努力和能力。

This is a US-Russian collaborative research project that will explore the isospin dependence of fragmentation and spallation reactions produced in 1 GeV proton induced reactions. The principal investigator is Dr. ManYee B. Tsang from Michigan State University. Her Russian collaborators are Dr. Lyudmila Andronenko and Dr. Mikhail Andronenko from the St. Petersburg Nuclear Physics Institute. This project will take advantage of the unique capabilities of both research groups. The US group pioneers the isoscaling analysis and modeling while the Russian group has accumulated 1 GeV proton induced fragmentation and spallation data on many different isotope targets over the past decades. This collaboration will further understanding of the global nature of the isoscaling phenomenon and possible extraction of the symmetry terms in the Nuclear Equation of State.This project in nuclear physics research fulfills the program objectives of bringing together leading experts in the U.S. and Central/Eastern Europe to combine complementary efforts and capabilities in areas of strong mutual interest and competence on the basis of equality, reciprocity, and mutuality of benefit.
