Relativistic Effects on Isovector Dipole Giant Resonanses

  • 摘要: 在相对论量子场论(QHD)的框架下,得到了相对论线性Vlasov方程.依此计算了球形核16O、40Ca、90Zr及208Pb的巨偶极共振的强度函数分布.结果表明,相对论效应是不可忽视的.计算得到的巨共振中心能量稍高于非相对论线性Vlasov方程给出的对应值,与实验结果比较都有较好的符合.对计算结果作了简要的讨论,发现核子有效质量和平均场自旅轨道耦合力对巨共振能量有重要影想. In the framework of relativistic quantum hadron dynamical (QHD) theory,under semiclassical approximation and taking into vacuum fluctuation, a relativistic Vlasov equation (RVE) has been derived. Using RVE and considering other relativistic effects, we have studied the isovector dipole giant resonances built on ground state in spherical nuclei.The main results show that the resonance energies for each multipole are larger than those obtained from the non-relativistic classical Vlasov approach...
