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.

这是一个美俄合作研究项目，将探索1GeV质子诱导反应中产生的碎裂和散射反应的同位旋依赖性。 主要研究者是Dr. ManYee B。来自密歇根州立大学的Tsang。 她的俄罗斯合作者是来自彼得堡核物理研究所的Lyudmila Andronenko博士和Mikhail Andronenko博士。 该项目将利用这两个研究小组的独特能力。 美国小组率先进行了等标度分析和建模，而俄罗斯小组在过去几十年中积累了许多不同同位素靶的1GeV质子诱导碎裂和空间碎片数据。 这项合作将进一步了解全球性的isoscaling现象和可能的提取对称项的核状态方程。这个项目在核物理研究实现了计划的目标，汇集了领先的专家在美国和中欧/东欧联合收割机互补的努力和能力，在强烈的共同利益和能力的基础上平等，互惠，互利互惠。
