摘要：

We present results of fully self-consistent Hartree-Fock-based random phase approximation calculations of the strength functions S(E) and centroid energies E-CEN of isoscalar (T = 0) and isovector (T = 1) giant resonances of multipolarities L = 0-3 in Ca-40 and Ca-48, using a wide range of commonly employed 18 Skyrme-type nucleon-nucleon effective interactions. We determined the sensitivities of E-CEN and of the isotopic differences E-CEN(Ca-48) - E-CEN(Ca-40) to physical quantities, such as nuclear matter incompressibility coefficient, symmetry energy density, and effective mass, associated with the Skyrme interactions and compare the results with the available experimental data.
