Low-lying dipole response in the stable ${}^{40,48}$Ca nuclei with the second random-phase approximation

D. Gambacurta, M. Grasso, F. Catara

Low-energy dipole excitations are analyzed for the stable isotopes ${}^{40}$Ca and ${}^{48}$Ca in the framework of the Skyrme-second random-phase approximation. The corresponding rando…
