Physics - Fisica

LETICIA CUNQUEIRO MENDEZ

Il Corso si propone di fornire le basi della Fisica Nucleare moderna, senza dimenticare i molteplici legami con altri campi della Fisica sia al livello fondamentale (dalla l'evoluzione stellare alla ricerca di segnali di nuova Fisica) e sia al livello applicativo (dalle applicazioni in campo medico a quelle in campo ambientale e dei beni culturali). L'esame finale comprendera`, oltre all'esame orale, la discussione di una tesina, con presentazione di una ventina di slides, su un argomento scelto tra quelli proposti, permettendo allo studente di approfondire un particolarecampo di interesse.

Meccanica quantistica, relatività, istituzioni di fisica nucleare e subnucleare

COMPLEMENTARY TOPICS LIST:

List of complementary topics for a short presentation at the exam: at most 15 slides and 20 minutes. You can propose a different argument, but it should be discussed and agreed in advance in terms of relevance for the course.

1) Modern theory approaches in nucleon-nucleon interaction.

2) Nuclear models: Fermi gas, Hartree-Fock, relativistic mean field.

The program of the course, lectures notes and slides, support material and references, are available on the Nuclear physics course e-learning home page.

The exam will consist in two parts: you will start first with a short presentation on a complementary topic of your choice (see course program section) for which you will have at most 20 minutes and you can use slides (max 15) or blackboard; in the second part of the exam you will be asked and questioned on two topics among the ones discussed during the lectures. The exam will last for about one hour in total.

The choice of the complementary topic should be agreed in advance with me: you will propose me one article or review, or book section from which your topic will develop, and will validate it before you start preparing it. You can choose among a list of complementary topics (see course program section). If you prefer choosing another topic of yours, please let me know in any case in advance for topic validation and then for the support material like in the general case.
