Regularization of zero-range effective interactions in finite nuclei
Marco Brenna, Gianluca Colò, Xavier Roca-Maza
The problem of the divergences which arise in beyond mean-field calculations, when a zero-range effective interaction is employed, has not been much considered so far. Some of us h…
A microscopic particle-vibration coupling approach for atomic nuclei. Giant resonance properties and the renormalization of the effective interaction
Marco Brenna
The self-consistent mean-field (SCMF) theory describes many properties of the ground state and excited states of the atomic nucleus, such as masses, radii, deformations and giant r…
A microscopic model beyond mean-field: from giant resonances properties to the fit of new effective interactions
M. Brenna, G. Colò, X. Roca-Maza +3
A completely microscopic beyond mean-field approach has been elaborated to overcome some intrinsic limitations of self-consistent mean-field schemes applied to nuclear systems, suc…
Nuclear Symmetry Energy: constraints from Giant Quadrupole Resonances and Parity Violating Electron Scattering
X. Roca-Maza, B. K. Agrawal, P. F. Bortignon +8
Experimental and theoretical efforts are being devoted to the study of observables that can shed light on the properties of the nuclear symmetry energy. We present our new results…
Electric Dipole Polarizability in Pb: insights from the Droplet Model
X. Roca-Maza, M. Centelles, X. Viñas +6
We study the electric dipole polarizability in Pb based on the predictions of a large and representative set of relativistic and non-relativistic nuclear mean field…
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…
The Gamow-Teller response within Skyrme random-phase approximation plus particle-vibration coupling
Yifei Niu, Gianluca Colo, Marco Brenna +2
Although many random-phase approximation (RPA) calculations of the Gamow-Teller (GT) response exist, this is not the case for calculations going beyond the mean-field approximation…
The pygmy dipole strength, the neutron radius of Pb and the symmetry energy
X. Roca-Maza, M. Brenna, M. Centelles +5
The accurate characterization of the nuclear symmetry energy and its density dependence is one of the outstanding open problems in nuclear physics. A promising nuclear observable i…
Microscopic theory of the γ-decay of nuclear giant resonances
Marco Brenna, Gianluca Colò, Pier Francesco Bortignon
In the past decades, the γ-decay of giant resonances has been studied using phenomenological models. In keeping with possible future studies performed with exotic beams, microscopi…
Low-lying dipole response: isospin character and collectivity in Ni, Sn and Pb
X. Roca-Maza, G. Pozzi, M. Brenna +2
The isospin character, the collective or single-particle nature, and the sensitivity to the slope of the nuclear symmetry energy of the low-energy isovector dipole response (known…
