Learning goals

In the specific field of this curricular unit (Nuclear and Particle Physics),students should acquire competences that allow them to:

- understand the involved physical phenomena and deepen that knowledge.

- solve problems using the acquired knowledge – communicate (with specialists and non-specialists) the interpretation of the questions and the solutions for the problems.

Syllabus

The essential interactions. Classification of particles: hadrons (baryons, mesons) and leptons; quarks; field mesons.

α, β and γ Radioactivity and electronic capture; nuclear fission and fusion. Law of radioactive decay. Rutherford Dispersion; concept of efficient section.

Nuclear force. Nuclear mass and binding energy. Yukawa theory.

Liquid drop model. Semi-empirical mass formula (Weizsacker) and nuclear stability. Fermi gas model. State density, Fermi momentum and energy. α Decay. Gamow’s Theory, selection rules and other Tunnelling processes.

Layer model. Spin-orbit interaction. Magnetic dipole moment, four-pole electric moment, deformed nucleus, collective excitations.

Electromagnetic transitions. Selection rules and transition probabilities. Isomerism. Weak interaction.

Beta decay and electron capture. Fermi model of beta decay. P and CP violation.

Pattern model. Feynman diagrams. Propagators. Weak interaction and field bosons. Leptons and quarks.

Quantum chromodynamics (gluons). Assymptotic freedom. Nuclear Physics applications: nuclear fission and fusion (Types of Nuclear Reactors; principles and applications); Nucleosynthesis.

Particle accelerators: principles and applications.

Medical applications: diagnosis and therapy.

Laboratorial component:

- α, β e γ spectroscopy (including Compton dispersion).

- annihilation of positrons.

- observation of cosmic radiation.

Teaching method

Three theoretical one-hour classes per week.

Support to the resolution of problems by students (an average of 2 hours per week).

Laboratorial assignments (an average of 1 hour per week), including the preparation of measures, the taking of data, the analysis of that data and the presentation of the conclusions (report and oral presentation).

Assessment based on:

- performance in the laboratory, reports and presentations.

- resolution of exercises that will be delivered throughout the semester.

- two (or three) midterm tests and final exam or a single final exam.
