87969 - NUCLEAR PHYSICS

Course Unit Page

Academic Year 2018/2019

Learning outcomes

At the end of the course the student will be introduced to the basic concepts of Nuclear Physics. He/she will gain a general comprehension of nuclear models, nuclear reactions and neutron spectroscopy. He/she will have a general understanding of phenomena like nuclear fusion and fission and will be able to solve basic problems invol ving typical situation where different nuclear energy ranges are involved.

Course contents

The course aims to provide the basic tools to understand all the dynamics and implications of nuclear physics. Whenever is possible the topics will be analyzed from a historical, theoretical and applicative point of view.

Prerequisites: Basic knowledge of quantum mechanics is required.

Program of the first part (Dr. Finelli):

Basic concepts of nuclear physics. Nuclear forces: empirical phase shifts and deuteron properties. Theoretical description of the nuclear potential. Basic approaches to the structure nuclei: ground and excited states. Theory of the compound nucleus. Radioactive decays: decay chains, half-lives, natural radioactivity, and radiation measurement. Beta decay: weak interaction, non-preservation of parity, decay rates, ft values, permitted processes, prohibited processes, selection rules, and double beta decay. Alpha decay: Gamow's theoretical approach, and selection rules. Gamma decay: electromagnetic moments, Schmidt lines, multipole expansion, selection rules, and Lande 's formula. Nuclear reactions and neutron scattering, neutron absorption and moderation. History of nuclear fission. Nuclear fission theory and phenomenology. (36 hours)

Program of the second part (Prof. Bruno) on heavy-ion reactions:

Reaction mechanisms: low energy (fusion, deep inelastic, direct reactions), relativistic range (participants and spectators model), and Fermi energy regime (peripheral and semi-central, neck structures, central collisions). Analysis tools: event selection, calorimetry and thermometry, and size and decay times of “sources”. Nuclear matter from zero to finite temperature. Accelerators and detecting systems for nuclear reaction experiments. Thermalization of nuclear systems formed in heavy ion collisions: pre-equilibrium emission and transport equation. Decay of hot nuclei: low energy processes (evaporation, giant resonances, fission), and high energy processes (fragmentation, vaporization). Nuclear fragmentation. Recent experiments at LNL and SPES. (16 hours)
