Systematics of the first 2 + excitation in spherical nuclei with the Skryme quasiparticle random-phase approximation

Abstract

We use the quasiparticle random-phase approximation (QRPA) and the Skyrme interactions SLy4 and SkM∗ to systematically calculate energies and transition strengths for the lowest 2+ state in spherical even-even nuclei. The SkM∗ functional, applied to 178 spherical nuclei between Z = 10 and 90, produces excitation energies that are on average 11% higher than… (More)
