英文摘要The mass-dependent symmetry energy coefficients a(sym)(A) has been extracted by analysing the heavy nuclear mass differences reducing the uncertainties as far as possible in our previous work. Taking advantage of the obtained symmetry energy coefficient a(sym)(A) and the density profiles obtained by switching off the Coulomb interaction in Pb-208, we calculated the slope parameter L-0.11 of the symmetry energy at the density of 0.11 fm(-3). The calculated L-0.11 ranges from 40.5 MeV to 60.3 MeV. The slope parameter L-0.11 of the symmetry energy at the density of 0.11 fm(-3) is also calculated directly with Skyrme interactions for nuclear matter and is found to have a fine linear relation with the neutron skin thickness of Pb-208, which is the difference of the neutron and proton rms radii of the nucleus. With the linear relation the neutron skin thickness Delta R-np of Pb-208 is predicted to be 0.15-0.21 fm.
