RUI: A Study of Heavy-Ion Reactions

这个项目研究核物理学中的问题。 在中等能量下，重离子碰撞会产生由中子和质子组成的热而致密的物质，就像人们预期的存在于恒星核心的物质一样。 该项目将使用过渡态理论研究这些反应，以产生计算机模拟，从而能够与实验数据进行直接比较。 在更高的能量下，相对论重离子碰撞会产生一种由核子、π介子和许多其他粒子组成的等离子体，类似于宇宙的早期状态。 为了研究这种状态，需要很好地理解核子，π介子和其他粒子之间的相互作用。 本计画将利用实验资料来推导核子-核子可分离势的解析式.

This project studies problems in nuclear physics. At intermediate energies heavy-ion collisions produce hot and dense matter composed of neutrons and protons, such as that expected to exist in the core of starts. This project will study those reactions using the transition state theory to produce a computer simulation that will enable a direct comparison with experimental data. At higher energies, relativistic heavy-ion collisions produce a plasma of nucleons, pions, and many other particles resembling an early state of the universe. To study this state, a good understanding of the interactions between nucleons, pions, and other particles is needed. This project will use experimental data to extract analytic expressions for the nucleon- nucleon separable potentials.
