| 中文摘要: |
| 利用基于微观核多体理论的计算以及近期实验数据得到的单核子动量分布,考虑了由于短程关联导致的高动量尾巴,计算了同位旋不对称物质物态方程动能部分的值.通过与基于自由费米气体模型计算的结果比较,发现考虑了短程关联的物态方程动能部分不再符合抛物线近似,且对称能四阶项有显著的影响. |
| 英文摘要: |
| Using distribution of single-nucleon momentum guided by well-known predictions of microscopic nuclear many-body theories and recent experimental data,it considers the high momentum tail due to Short-Range Correlation and calculates the kinetic energy of isospin-asymmetric matter.By comparing with the results calculated by the Free Fermi Gas model,it is found that the kinetic energy part of the equation of the Short-Range Correlation is no longer in agreement with the parabolic approximation and the quartic term has a significant effect. |
