Atomic and Molecular Physics
Objectives
The aim of theoretical and theoretical-practical classes is to understand the concepts and physical processes, emphasizing rigor in language and the application of knowledge to the equation and methodical resolution of real problems.
The purpose of laboratory classes is to learn experimental methods related to atomic and molecular physics, systematize the collection and treatment of experimental results and the preparation of scientific reports.

Teaching method
The subject of the class is organized into theoretical classes, in which the course material will be presented, including application examples, and theoretical-practical classes, in which concrete problems are discussed with students, and laboratory classes where experiments are carried out and analyzed.
