核化学和力学不稳定性与核的液-气相变

Nuclear Chemical and Mechanical Instability and the Liquid-Gas Phase Transition in Nuclei

S. J. Lee, A. Z. Mekjian

摘要:

在平均场模型中,利用Skryme相互作用研究了原子核的热力学性质。本文研究了从纯中子系统到纯质子系统的质子分数全范围内的两组分系统的性质。除了体积、对称性和库仑效应之外,我们还包括动量或速度相关的力。应用的结果开发,然后给出其中包括核的机械和化学不稳定性和相关的液体/气体相变在两个组件系统。速度依赖性导致共存曲线和核力学和化学不稳定性曲线的进一步变化。

英文摘要:

The thermodynamic properties of nuclei are studied in a mean field model using a Skryme interaction. Properties of two component systems are investigated over the complete range of proton fraction from a system of pure neutrons to a system of only protons. Besides volume, symmetry, and Coulomb effects we also include momentum or velocity dependent forces. Applications of the results developed are then given which include nuclear mechanical and chemical instability and an associated liquid/gas phase transition in two component systems. The velocity dependence leads to further changes in the coexistence curve and nuclear mechanical and chemical instability curves.
