Giant resonances in Ca-40 and Ca-48
Additional Document Info
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 40Ca and 48Ca, 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 (48Ca) - E CEN (40Ca) 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. 2013 American Physical Society.
