Anharmonic vibrations in nuclei
Fallot, M.; Chomaz, Philippe; Andrés Martín, María Victoria; Catara, Francesco; Lanza, Edoardo G.; Scarpaci, J. A. (Elsevier, 2003-12-29)We show that the non-linearities of large amplitude motions in atomic nuclei induce giant quadrupole and monopole vibrations. ...

Microscopic nuclear form factor for the pygmy dipole resonance
Lanza, Edoardo G.; Vitturi, Andrea; Andrés Martín, María Victoria; Catara, Francesco (EDP Sciences, 2016)Pygmy dipole resonance can be populated via isoscalar probes due to the strong mixing of isoscalar and isovector components. ...

Nuclear excitations as coupled one and two random-phase-approximation modes
Gambacurta, Danilo; Catara, Francesco; Grasso, M.; Sambataro, M.; Andrés Martín, María Victoria; Lanza, Edoardo G. (American Physical Society, 2016)We present an extension of the random-phase approximation (RPA) where the RPA phonons are used as building blocks to ...
