Nuclear Reaction Dynamics

国际重离子研究所建议开展重离子理论物理研究。这一建议的重点是反应动力学，从中等能量(10毫微伏)到超相对论能量(100毫微伏)。特别关注与NSCL、GSI、CERN-SPS和RHIC实验有关的理论。与美国和国外的实验小组合作有着悠久的传统，他们将继续这样做。主要重点是研究发射粒子之间的关联，以及不同能量下重离子反应中的相变。这一建议的一个重要组成部分是为未来的稀有同位素加速器(RIA)计划及其与核天体物理的联系提供理论支持。由于RIA建设被列为NSAC远景计划的重中之重，深化这一领域的理论基础是必要的。鉴于目前的实验情况，所提出的课题是研究人员感兴趣的。投资者的一个传统优势是能够使他们的研究方向适应新的实验基金，可以预测这种能力将在拟议的资助期内持续下去。几乎所有拟议的资金都将用于支付两名研究生和一名博士后助理的工资。在第一年，需要一些计算机支持。这是合理的，因为几乎所有提出的研究都广泛使用了数值计算。

The PI's propose to conduct research on theoreticalheavy ion physics. The emphasis of this proposal is reaction dynamics over arange of beam energies, from intermediate ( 10 AMeV) to ultra-relativistic(100 AGeV). Particular attention is paid to theory that is relevant to exper-iments at the NSCL, GSI, CERN-SPS, and RHIC. The co-PIs have a longtradition of collaborating with experimental groups in the US and abroad,and they will continue to do so.Thematically, themain emphasis lies on the investigation of correlationsbetween emitted particles, as well as phase transitions in heavy ion reactionsat different energy regimes. An important component of this proposal is thetheoretical support for the future Rare Isotope Accelerator (RIA) programand its connection to nuclear astrophysics. Since the RIA construction wasidentifed as the highest priority in theNSAC long-range plan, it is impera-tive to deepen the theoretical underpinning for this feld.The proposed topics are of present interest to the investigators in lightof the present experimental situation. A traditional strength of the investi-gators is the ability to adapt their research directions to new experimentalfndings, and it can be predicted that this will continue during the proposedgrant period.Almost all of the funds proposed will be spent for salaries for two gradu-ate students and one post-doctoral associate. In year one, there is a requestfor some computer support. This is justifed, because almost all proposedresearch makes extensive use of numerical work.
