Nuclear equation of state and compression modes Academic Article uri icon


  • The nuclear matter (N = Z and no Coulomb interaction) incompressibility coefficient, Knm, which is directly related to the curvature of the nuclear matter equation of state, is a very important physical quantity in the study of properties of nuclei, supernova collapse, neutron stars and heavy-ion collisions. We review the current status of Knm and the experimental and theoretical methods used to determine the value of Knm from the excitation cross-sections (E) and the transition strength distributions S(E) of compression modes in nuclei. In particular, we will consider the isoscalar giant monopole resonance (ISGMR) and the isoscalar giant dipole resonance (ISGDR) and provide a simple explanation to the long standing problem of the conflicting results obtained for Knm, deduced from experimental data on excitation cross sections for the ISGMR and data for the ISGDR.
