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 report
