Abstract：
Nuclear matter incompressibility is discussed by the monopole compression modes in nuclei in the framework of a fully consistent relativistic random phase approximation, based on effective Lagrangians with a mixed isoscalar-isovector nonlinear coupling term. A predicted value of the matter incompressibility coefficient is given by comparison between experimental and calculated energies of the isoscalar giant monopole resonance (ISGMR) in nuclei ²⁰⁸Pb, ¹⁴⁴Sm, ¹¹⁶Sn and ⁹⁰Zr. The new isoscalar-isovector nonlinear coupling softens the nuclear matter symmetry energy without ruining the agreement with experimentally existing ground state properties. The effect of the softening of the symmetry energy on the ISGMR is discussed.
