69. Gamma-ray spectroscopy in the vicinity of 68Ni and 100Sn using the EXOGAM array

Dr Gilles de FRANCE (GANIL)

Invited talk

EXOGAM is installed at GANIL since 2001 and is extensively used in the various experimental areas. In the last years, we have a performed a serie of experiments using deep inelastic reactions in inverse kinematics. Excited states in neutron rich nuclei around 68Ni have been studied using the EXOGAM array in coincidence with the VAMOS large acceptance spectrometer. The evolution of...

Contribution talk

We have carried out systematic calculations of the electric dipole modes up to mass A=110 region using Skyrme-Hartree-Fock plus RPA approach in fully self-consistent manner. We solved the RPA equation in 3D coordinate space for both spherical and deformed nuclei. We found that the low-angular momentum orbit in neutron-rich nuclei is a key ingredient for emergence of low-lying dipole mode,...

17. Pygmy dipole resonance of radio isotopes around r-process

Contribution talk

We investigate pygmy dipole resonance(PDR) of radio isotopes systematically with the canonical-basis time-dependent Hartree-Fock-Bogoliubov theory (Cb-TDHFB). The Cb-TDHFB is a new time-dependent method which is derived from TDHFB with a BCS approximation for pairing correlation. The results of this method is a very good approximation of quasi-particle random phase approximation, and they...
