A STUDY ON THE PHASE STRUCTURE OF ASYMPTOTIC SYMMETRIC NUCLEAR MATTER

Abstract

The strong and dense interaction matter has attracted physicists’ attention for a long time. The phase transition of the nuclear matter has been investigated in many theoretical papers. The studies have been based on the phenomenological models directly established from the nucleon degrees of freedom. The models of non-relativistic nuclei using different forms of the nucleon-nucleon interaction potential energy have gained much success in the study on nuclear materials at a low density and low power. However, the theory of non-relativistic nuclei failed to reflect the physical properties of the solidified materials. This paper studies the properties of nuclear matter based on the model of asymptotic symmetric nuclear matter, taking into account the scalar-vector interactions and clearly describes the scenario of the first-class gas-liquid phase transition of the nuclear matter under saturation density.
