| 英文摘要 | Nuclear structure observables usually most effectively probe the properties of nuclear matter at subsaturation densities rather than at saturation density. We demonstrate that the electric dipole polarizibility alpha(D) in Pb-208 is sensitive to both the magnitude E-sym(rho(c)) and density slope L(rho(c)) of the symmetry energy at the subsaturation cross density rho(c) = 0.11 fm(-3). Using the experimental data of alpha(D) in Pb-208 from RCNP (Research Center for Nuclear Physics, Osaka University) and the recent accurate constraint of E-sym(rho(c)) from the binding energy difference of heavy isotope pairs, we extract a value of L(rho(c)) = 47.3 +/- 7.8 MeV. The implication of the present constraint of L(rho(c)) to the symmetry energy at saturation density, the neutron skin thickness of Pb-208 and the core-crust transition density in neutron stars is discussed. |
