Beyond the mean field in the particle-vibration coupling scheme
M. Baldo, P. F. Bortignon, G. Colo' +2
The Energy Density Functional theory is one of the most used methods developed in nuclear structure. It is based on the assumption that the energy of the ground state is a function…
Giant Quadrupole Resonances in 208Pb, the nuclear symmetry energy and the neutron skin thickness
X. Roca-Maza, M. Brenna, B. K. Agrawal +5
Recent improvements in the experimental determination of properties of the Isovector Giant Quadrupole Resonance (IVGQR), as demonstrated in the A=208 mass region, may be instrument…
Sum Rules of the Multiple Giant Dipole States
H. Kurasawa, T. Suzuki, P. F. Bortignon
Various sum rules for multiple giant dipole resonance states are derived. For the triple giant dipole resonance states, the energy-weighted sum of the transition strengths requires…
Attractive and repulsive contributions of medium fluctuations to nuclear superfluidity
G. Gori, F. Ramponi, F. Barranco +4
Oscillations of mainly surface character (S=0 modes) give rise, in atomic nuclei, to an attractive (induced) pairing interaction, while spin (S=1) modes of mainly volume character…
Pairing Matrix Elements and Pairing Gaps with Bare, Effective and Induced Interactions
F. Barranco, P. F. Bortignon, R. A. Broglia +4
The dependence on the single-particle states of the pairing matrix elements of the Gogny force and of the bare low-momentum nucleon-nucleon potential is studied in the…
Dipole states in stable and unstable nuclei
D. Sarchi, P. F. Bortignon, G. Colo`
A nuclear structure model based on linear response theory (i.e., Random Phase Approximation) and which includes pairing correlations and anharmonicities (coupling with collective v…
