Description

Low-energy dipole excitations in Neon isotopes and N=16 isotones are calculated with a fully consistent axially-symmetric-deformed Quasi-particle Random Phase Approximation (QRPA) approach based on Hartree-Fock-Bogolyubov (HFB) states. The same Gogny D1S effective force has been used both in HFB and QRPA calculations. The microscopical structure of these low-lying resonances, as well as the behavior of proton and neutron transition densities are investigated in order to determine the isoscalar or isovector nature of the excitations.
