| 英文摘要 | Within the isospin dependent Brueckner-Hartree-Fock framework, the proton and neutron single particle potentials in isospin asymmetric nuclear matter as well as their isospin denpendence have been investigated. The symmetry potential is extracted from the proton and neutron single nucleon potentials. The symmetry potential turns out to depend strongly on both momentum and density, while it is almost independent of the isospin asymmetry. The density and momentum dependence of the predicted symmetry potential has been compared with the phenomenological parameterizations adopted in the BUU simulations of the heavy ion collisions induced by neutron-rich nuclei. It is found that the microscopic symmetry potential shows a completely different momentum and density dependence from the phenomenological ones and thus the present results are useful for putting a strict constraint on the phenomenological models for the symmetry potential. |
