| 英文摘要 | We have studied the isoscalar giant quadruple resonance (ISGQR) and the isovector giant dipole resonance (IVGDR) in Pb-208 based on an improved isospin-dependent Boltzmann-Uehling-Uhlenbeck transport approach using an improved isospin- and momentum-dependent interaction. With the isoscalar nucleon effective mass and the nucleon-nucleon cross section which reproduces respectively the excitation energy and the width of the ISGQR strength function, the slope parameter of the symmetry energy and the neutron-proton effectivemass splitting are constrained respectively within 36 < L < 62 MeV and 0.08 delta < (m(n0)* - m(p0)*)/m < 0.42 delta, by comparing the resulting centroid energy of the IVGDR and the electric-dipole polarizability with the experimental data. It is found that nucleon-nucleon collisions have considerable effects on the resulting electric-dipole polarizability, which needs to be measured more accurately in order to pin down isovector nuclear interactions. |
