在Dirac Brueckner Hartree-Fock(DBHF)理论框架下研究了核子光学势和核子有效质量的同位旋相关性．非对称核物质的计算采用了DBHF的核子自能的Dirac结构的新的分解方法,核子自能的实部是用G矩阵在Hartree-Fock近似下计算得到,而虚部从极化图得到．用核子的薛定谔等价势可以得到核子矢量有效质量．研究表明考虑了核势的能量相关性在丰中子核物质情况下核子矢量有效质量比质子的大．
In the framework of Dirac Brueckner Hartree-Fock (DBHF) theory, the isospin dependence of the nuclear optical potential and the effective mass of the nucleus is studied. The asymmetric nuclear material is calculated using the new decomposition method of the Dirac structure of the nuclear self-energy of DBHF. The real part of the nuclear self-energy is calculated by using the Hartree-Fock approximation of the G matrix and the imaginary part is obtained from the polarization diagram. Using the Schrödinger equivalent energy of the nucleus, the effective mass of the nucleus vector can be obtained. Studies have shown that considering the energy dependence of the nuclear potential, the effective mass of the nuclear vector is larger than that of the proton in the case of a neutron rich matter.
