Goal of the course
The course is addressed to fourth year physics undergraduate students and has a main goal to introduce them to the basic concepts of atomic and molecular physics as well as the interaction of matter with radiation. In combination with the course Quantum Mechanics II (Structure of Matter) this course covers adequately the knowledge a student must have mastered in order to study in a more advanced theoretical or experimental level topics of physics of materials. It is recommended that a student has good command of the material covered in the courses Modern Physics I (Φ-201) and Quantum Mechanics I (Φ-301).
