Abstract：
The saturating chiral breaking field theory are used to study the compressibility of the Fermi-liquid and the excitation energies of the giant monopole and quadrupole states in the framework of mean-field theory.It is found that the compressibility of the Fermi-liquid in the nuclear system,and the excitation energies of the giant monopole and quadrupole states are more close to the experimental values in comparison with the results of the σ-ω model.
