| 英文摘要 | The effect of tensor force on the density dependence of nuclear symmetry energy has been investigated within the framework of the Brueckner-Hartree-Fock (BHF) approach. It is shown that the tensor force manifests its effect via the tensor (SD1)-S-3 channel. The density dependence of symmetry energy E-sym turns out to be determined essentially by the tensor force from the pi meson and rho meson exchanges via the (SD1)-S-3 coupled channel. Increasing the strength of the tensor component due to the rho-meson exchange tends to enhance the repulsion of the equation of state of symmetric nuclear matter and leads to the reduction of symmetry energy. The present results confirm the dominant role played by the tensor force in determining nuclear symmetry energy and its density dependence within the microscopic BHF framework. |
