| 英文摘要 | We investigate the equation of state of asymmetric nuclear matter and its isospin dependence in various spin-isospin ST channels within the framework of the Brueckner-Hartree-Fock approach extended to include a microscopic three-body force (TBF). It is shown that the potential energy per nucleon in the isospin-singlet T = 0 channel is mainly determined by the contribution from the tensor SD coupled channel. At high densities, the TBF effect on the isospin-triplet T = 1 channel contribution turns out, to be much larger than that on the T = 0 channel contribution. At, low densities around and below the normal nuclear matter density, the isospin dependence is found to come essentially from the isospin-singlet, SD channel and the isospin-triplet, T = I component is almost independent, of isospin asymmetry. As the density increases, the T = 1 channel contribution becomes sensitive to the isospin asymmetry and at high enough densities its isospin dependence may even become more pronounced than that of the T = 0 contribution. The present results may provide some microscopic constraints for improving effective nucleon-nucleon interactions in a nuclear medium and for constructing new functionals of effective nucleon-nucleon interaction based oil microscopic many-body theories. |
