An introductory course in atomic physics, such as PHYS2B24, and an introductory course in quantum physics, such as ASTR2B11, PHYS2B22, or their equivalents in other departments.
Aim of the Course
The aim of the course is to provide an introduction to the physical concepts of nuclear and particle physics and the experimental techniques which they use.
After completing the course, students should:

Methodology and Assessment
The course consists of 30 lectures supplemented by 3 lecture periods for coursework problems and other matters as they arise. Assessment is based on an unseen written examination (90%) and the best 4 of 5 coursework problem papers (10%).
