Qrpa Approach

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 behavior of proton and neutron transition densities is presented in order to determine the isoscalar or isovector nature of the excitations.
