| Abstract: | The isovector giant dipole resonance energies of 90Zr, 144Sm, and 208Pb, the pygmy resonance strengths and their exhausted energy-weighted sum rules of 68Ni and 132Sn, and the anti-analog giant dipole resonance of 208Pb as well as its isobaric analog state have been measured experimentally．The collective excited properties of finite nuclei are calculated in relativistic and non-relativistic mean field methods with different effective interactions．Compared to the experimental data, the density dependence of symmetry energy can be extracted． |
