NUCLEI AND PARTICLES
LEARNING OUTCOMES OF THE COURSE UNIT
At the end of this course, the student is expected to:
- know the fundamental properties of matter at the nuclear and subnuclear scale;
- know the main experimental methods employed in nuclear and particle physics;
- know the main experiments of the past and understand their conceptual impact on the advance of knowledge;
- being able to compute cross sections and decay rates for simple processes;
- being able to apply symmetry principles and conservation laws to problems of nuclear and particle physics.
Basic knowledge of classical physics, quantum mechanics and special relativity.

ASSESSMENT METHODS AND CRITERIA
The evaluation of the student's learning will be articulated in two parts:
1) a written test, divided in two sections: a multiple choice quiz and some exercises.
2) an interview on the subjects of the course.
During the course there will be two intermediate written tests. If both of them are passed, the student may opt for skipping the written test "1)" above.
The final evaluation will be obtained by summing the results of the written tests to +/- 3 points obtained from the oral exam.
Classroom discussions, lead by students, of the exercises assigned as homework.
