Isovector channel of quark-meson-coupling model and its effect on symmetry energy
2011 (English)In: Nuclear Physics A, ISSN 0375-9474, Vol. 865, no 1, 57-68 p.Article in journal (Refereed) Published
The non-relativistic approximation Of the quark-meson-coupling model has been discussed and compared with the Skyrme-Hartree-Fock model which includes spin exchanges. Calculations show that the spin-exchange interaction has important effect on the descriptions of finite nuclei and nuclear matter through the Fock exchange. Also in the quark-meson-coupling model, it is the Fock exchange that leads to a nonlinear density-dependent isovector channel and changes the density-dependent behavior of the symmetry energy.
