Introduction to Atomic and Molecular Physics

(18797)

Requirements (Subjects that are assumed to be known)

Classical physics (Mechanics and Electromagnetism). Basic modern and quantum physics

The course is an introduction to the subject for physicists and engineers that have not taken a full course on quantum mechanics, and a preliminary to more advanced courses on atomic and molecular physics and dynamics, as a mean to acquire a heuristic comprehension of the topics. For this purpose, principal ideas of wave mechanics are introduced, followed by elementary presentations of methodological aspects, as well of descriptions of atomic and molecular structure and interactions.

Skills and learning outcomes

Description of contents: programme

1.- Introduction to quantum mechanics. Theoretical basis of atomic and molecular physics
