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 nonspecialists) 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. Semiempirical 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. Spinorbit interaction. Magnetic dipole moment, fourpole 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. Prerequisites

Three theoretical onehour 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.
