Characterization of vorticity in pygmy resonances and soft-dipole modes with two-nucleon transfer reactions
The properties of the two-quasiparticle-like soft E1-modes and Pygmy Dipole Resonances (PDR) have been and are systematically studied with the help of inelastic and electromagnetic experiments which essentially p...

Radioactive beams and inverse kinematics: Probing the quantal texture of the nuclear vacuum
The properties of the quantum electrodynamic (QED) vacuum in general, and of the nuclear vacuum (ground) state in particular, are determined by virtual processes implying the excitation of a photon and of an e...

Dual origin of pairing in nuclei
The pairing correlations of the nucleus 120Sn are calculated by solving the Nambu–Gor’kov equations, including medium polarization effects resulting from the interweaving of quasiparticles, spin and density vibra...

Nuclear field theory predictions for 11Li and 12Be: Shedding light on the origin of pairing in nuclei
Recent data resulting from studies of two-nucleon transfer reaction on 11Li, analyzed through a unified nuclear-structure-direct-reaction theory have provided strong direct as well as indirect confirmation, throu...

Mean field and beyond in nuclei far from stability lines
We calculate, for the first time, the state-dependent pairing gap of a finite nucleus (120Sn) diagonalizing the bare nucleon-nucleon potential (Argonne v 14) in a Hartree-Fock basis. The resulting gap accounts fo...

Many-body effects in nuclear structure
We calculate, for the first time, the state-dependent pairing gap of a finite nucleus (120Sn) diagonalizing the bare nucleon-nucleon potential (Argonne v 14) in a Hartree-Fock basis (with effectiv...

Superfluidity in the inner crust of neutron stars
We present a mean-field quantum calculation of the specific heat in the inner crust of neutron stars, taking into account the inhomogeneous character of the system, in which a lattice of neutron-rich nuclei co...

Pairing in exotic and in stable nuclei
The exchange of low-lying collective vibrations between pairs of nucleons moving in time reversal states close to the Fermi energy provides a conspicuous contribution to the nuclear pairing interaction, which ...

Sources of Pairing in Nuclei
We discuss the different contributions to the pairing interaction acting among nucleons moving in time-reversal states close to the Fermi energy and the consequences it may have on the transition taking place ...

The halo of the exotic nucleus 11Li: a single Cooper pair
If neutrons are progressively added to a normal nucleus, the Pauli principle forces them into states of higher momentum. When the core becomes neutron saturated, the nucleus expels most of the wave function of...

Multistep rotational energy correlations probed by high fold $γ$ coincidence data
The number of discrete rotational bands in the nucleus 168Yb is obtained by a fluctuation analysis of the rotational ridge structure in double and triple γ coincidence matrices. The data are compared with cranke...

From discrete rotational bands to damped rotational motion
We present shell model calculations for warm rotating nuclei, combining the cranked Nilsson mean field and a residual surface-delta two-body interaction. The model is used to describe the transition from the r...

Scars of discrete rotational bands in hot nuclei
Rotational motion loses its coherence as a function of the nuclear internal excitation energy. The dam** process does not proceed in a continuous fashion and scars of discrete rotational bands are found, inb...

Momentum distributions in halo nuclei
From the analogy between the break-up of weakly bound, neutron-rich nuclei and the phenomenon of optical diffraction, it is possible to formulate a model for the momentum distribution of both the core and the ...
