Abstract
Centroid energies, \(E_{\textrm{CEN}}\), of the isoscalar (\(T=0\)) and isovector (\(T=1\)) giant resonances of multipolarities \(L_{m}=0\)–3 in \({}^{\mathrm{40,48}}\)Ca, \({}^{\mathrm{68}}\)Ni, \({}^{\mathrm{90}}\)Zr, \({}^{\mathrm{116}}\)Sn, \({}^{\mathrm{144}}\)Sm, and \({}^{\mathrm{208}}\)Pb, were calculated within the fully self-consistent spherical Hartree–Fock (HF)-based random-phase approximation (RPA) theory, using 33 different energy density functionals associated with Skyrme-type effective nucleon–nucleon interactions of the standard form commonly employed in the literature. We also calculate the Pearson linear correlation coefficients between each \(E_{\mathrm{CEN}}\) and each bulk property of nuclear matter (NM), associated with the Skyrme interactions used in the calculations, and determine the sensitivity of \(E_{\mathrm{CEN}}\) to bulk properties of NM. By comparing the calculated values of \(E_{\textrm{CEN}}\) to the experimental data, we constrain the values of the bulk NM properties. We find that interactions associated with the values of the NM effective mass, \(m^{\ast}/m=0.70\)–0.90, incompressibility coefficient, \(K_{\textrm{NM}}=210\)–240 MeV, and the enhancement coefficient of the energy-weighted sum rule of the isovector giant dipole resonance, \(\kappa=0.25\)–0.70, best reproduce the experimental data.
