Deducing the nuclear matter incompressibility coefficient from data on isoscalar compression modes
نویسندگان
چکیده
Accurate assessment of the value of the incompressibility coefficient, K, of symmetric nuclear matter, which is directly related to the curvature of the equation of state (EOS), is needed to extend our knowledge of the EOS in the vicinity of the saturation point. We review the current status of K as determined from experimental data on isoscalar giant monopole and dipole resonances (compression modes) in nuclei, by employing the microscopic theory based on the Random Phase Approximation (RPA).

Isoscalar Giant Dipole Resonance and Nuclear Matter Incompressibility Coefficient
Studies of compression modes of nuclei are of particular interest since their strength distributions, S(E), are sensitive to the value of the nuclear matter incompressibility coefficient, K [1]. At present, Hartree-Fock (HF) based random-phase-approximation(RPA) calculations for the isoscalar giant monopole resonance (ISGMR) reproduce the experimental data for effective interactions associated ...
متن کاملTheoretical understanding of the nuclear incompressibility : where do we stand ?
The status of the theoretical research on the compressional modes of finite nuclei and the incompressibility K∞ of nuclear matter, is reviewed. It is argued that the recent experimental data on the Isoscalar Giant Monopole Resonance (ISGMR) allow extracting the value of K∞ with an uncertainity of about ± 12 MeV. Non-relativistic (Skyrme, Gogny) and relativistic mean field models predict for K∞ ...

متن کاملIsoscalar compression modes in relativistic random phase approximation
A fully consistent relativistic RPA calculation is performed for the monopole and dipole compression modes in nuclei. The emphasis is put on the effects of Dirac sea states which are generally neglected in relativistic RPA calculations. It is found that these effects can be quite important for the isoscalar monopole mode. The main contributions from the pairs of Fermi to Dirac sea states are th...
متن کاملIsoscalar dipole mode in relativistic random phase approximation
The isoscalar giant dipole resonance structure in Pb is calculated in the framework of a fully consistent relativistic random phase approximation, based on effective mean-field Lagrangians with nonlinear meson self-interaction terms. The results are compared with recent experimental data and with calculations performed in the HartreeFock plus RPA framework. Two basic isoscalar dipole modes are ...
