## Prof. A.M. Fox

### Autumn Semester, 20 lectures, 10 credits

This third year core module covers the quantum theory
of atoms and atomic spectra,
and also the basic principles of lasers.

PHY332 covers the quantum theory of simple atoms
and atomic spectra, and also the basic principles
of lasers.
The first part of the course covers the physics
of atoms and atomic spectra, beginning with
hydrogen and then moving on to multi-electron atoms.
The second part gives an introduction to laser
physics, with emphasis on the basic principles
of amplification by stimulated emission.

The aims of the course are as follows:

- to understand the quantum theory of the hydrogen atom
and other simple atoms;
- to describe the main features of atomic spectra ;
- to understand the basic principles of laser operation;

The written examination will contain 5 questions.
Candidates are exepcted to answer three questions.
Question 1 is compulsory and consists of several short parts
covering the whole syllabus. Candidates may then choose any two
from the remaining four questions which cover parts of the syllabus
in more detail.
