Research in Theoretical Nuclear Physics

本课题为重离子反应的理论研究。这些研究人员先前的工作表明，对碎片动量的分析可以提供有关初级反应产物的温度和密度的信息；对相关关系的分析提供了关于解体产物的大小及其与原始碰撞中心的距离的信息。建议研究对核化学如此重要的大质量传递（不完全聚变）的力学，并追溯碰撞过程的多步分量，试图找到一个高密度的区域来测试状态方程。此外，Balantekin建议在一个时间相关的电磁场中观察轻子的产生，看看这是否对在这些反应中观察到的异常带电粒子发射有任何启示，并再次研究可以对中微子振荡施加的限制。

This project is theoretical research on heavy ion reactions. Previous work by these investigators showed that analysis of fragment momenta gives information on the temperature and density of the primary reaction products; analysis of correlations gives information on the size of the disintegrating product and of its distance from the original center of collision. It is proposed to look into the mechanics of large mass transfer (incomplete fusion), so important for nuclear chemistry, and to trace back the multistep components of the collision process to try to find a region of high density which could test the equation of state. In addition, Balantekin proposes to look at lepton production in a time dependant electromagnetic field to see if this throws any light on the anomalous charged particle emission observed in these reactions, and to look again at the restrictions that can be placed on neutrino oscillations.
