密度相关对称能对椭圆流的影响
Influence of density dependent symmetry energy on Elliptical flow
摘要:
利用基于同位旋的量子分子动力学模型(IQMD)研究了密度相关对称能对椭圆流的影响。本文用约化的同位旋相关截面和硬(H)状态方程研究了在50 - 1000 MeV/核子能量范围内椭圆流对对称能的敏感性。椭圆流在称为过渡能的特定能量处变为零。一个系统的努力已经取得了钉下的密度依赖的对称能的跃迁能。
英文摘要:
The effect of density dependent symmetry energy on elliptical flow is studied using isospin-dependent quantum molecular dynamics model(IQMD). We have used the reduced isospin- dependent cross-section with hard(H) equation of state to study the sensitivity of elliptical flow towards symmetry energy in the energy range of 50 - 1000 MeV/nucleon. The elliptical flow becomes zero at a particular energy termed as transition energy. A systematic effort has been made to pin down the transition energy for the density dependent symmetry energy.
