Nuclear Breathing Mode in the Relativistic Mean-Field Theory
  The breathing-mode giant monopole resonance is studied within the framework of the relativistic mean-field (RMF) theory. Using a broad range of parameter sets, a systematic analysis of constrained incompressibility and excitation energy of isoscalar monopole states in finite nuclei is performed. A comparison is made with the incompressibility derived from the semi-infinite nuclear matter and with constrained nonrelativistic Skyrme Hartree-Fock calculations. Investigating the dependence of the breathing-mode energy on the nuclear matter incompressibility, it is shown that dynamical properties of surface respond differently in the RMF theory than in the Skyrme approach.
