Nuclear structure

Nuclear structure

Lectures will concern the study of modern aspects of the structure of nuclei in the ground state
and excited states. The course is divided in two parts, experimental and theoretical (respectively).
Theory (G.Colò, 12 hours):
Density functional methods in nuclear physics
Among microscopic methods, those based on Density Functional Theory can be applied to most
of nuclei along the periodic table. They are also useful for extrapolations towards uniform matter
(for instance, neutron stars).

Program:
-
Introduction and formalism, with a review of the Kohn
-
Sham theory for electronic systems
-
Applications to the nuclear ground state (binding energies, radii, superfluidity)
-
Theory for excited states: the time
-
dependent density functional theory with applications
-
Covariant (or “relativistic”) functionals
-
Possibile extensions of the model. The problem of isospin in nuclear physics: conservation,
breaking and restoration Experiment (S.Leoni, 12 hours):
Nuclear Struct ure studied with Stable and
radioactive beams
Nuclear Structure properties will be discussed from a phenomenological/experimental point of
view, mostly in connection with the present use of accelerated beams of stable and radioactive
heavy ions.

Program:
-
Production techniques for exotic beams
-
2 hours;
-
High precision Mass measurements with Penning traps
-
Collective modes of rotation at finite temperature
-
Collective modes of vibration: Giant Resonances
-
Lifetime measurements of excited states by gamma spectroscopy
