The Research Activity of the Naples Unit
Our research focuses essentially on the influence of many-body correlations on the
nuclear structure properties. Particular attention is devoted to the microscopic origin of the
effective interaction that binds neutron and protons in finite nuclei, as originating from the
nuclear-medium renormalizations of the bare potential.
Our specific research lines are:

shell-model studies of nuclear structure properties with effective interactions derived
from chiral and low- momentum potentials by means of the Q-box perturbative
technique. We investigate (i) properties of exotic nuclei near doubly magic nuclei, with
particular attention to their spectroscopic factors, owing to the great relevance of oneand two-nucleon transfer reactions in the study of RIBs.; (ii) chains of nuclei toward
the neutron drip line, to study the evolution of the shell structure and collectivity as a
function of the neutron-proton asymmetry;

the theory of effective interaction. In particular, we intend (i) to study of the effects of
three-body forces on the properties of complex nuclei making use of a chiral 3-body
interaction; (ii) to investigate the role of many body correlations in systems with more
than two valence nucleons; (iii) to better understand the microscopic origin of the
properties of the shell-model interaction by analyzing the various steps involved in the
derivation of realistic effective interactions;

new algorithms for large scale calculations which makes it possible to truncate
effectively the shell model space;

the fine structure of giant and pygmy resonances, mainly in neutron rich O and Sn
isotopes, through an equation of motion phonon method (EMPM), based on
microscopic multiphonons, which greatly simplifies the process of constructing and
diagonalizing the full nuclear Hamiltonian;
Part of our research activity concerns nuclear matter. We intend to continue our work on the
dependence on the infinite neutron matter from the regulator of the chiral interaction and
extend this kind of studies to proton-neutron matter. We plan to use the obtained EOS in the
study of neutron stars.
We have several international collaborations with theory and experimental groups of
Universities and Laboratories in Europe and USA.
Since 1986 we have organized every two and, later, three years ten International Conferences
in Naples areas, which have become one of the most attended meetings by the international
comunity of nuclear physicists. The conferences offered to both theorist and experimentalists
a great opportunity to discuss the most important advances and promising perspectives in
nuclear structure. We are now organizing the 11th International Spring Seminar on Nuclear
Physics: SHELL MODEL AND NUCLEAR STRUCTURE: achievements of the past two decades, in
honor of Aldo Covello, which will be held in Ischia from May 12 to 16, 2014.
