Nuclear and Particle Physics module (PH42006)

What holds the nucleus of an atom together? What happens during radioactive decay? What are the smallest building blocks of the universe? This module introduces you to nuclear and particle physics. It looks at the forces and processes that shape matter at its most fundamental level.

You’ll begin with how we study the atomic nucleus, learning about nuclear sizes, shapes, and scattering. You’ll discover how models like the liquid drop and shell model help us understand nuclear structure. You'll also look at how decay processes like alpha, beta, and gamma radiation reveal the forces at play.

You'll then investigate nuclear reactions. These include fission and fusion. You'll learn how these processes power stars, nuclear reactors, and the search for clean energy on Earth.

This leads on to how scientists and engineers are working to overcome the challenges of fusion power. It's seen as one of the most promising technologies for future energy production.

Then, you’ll study the subatomic world to explore elementary particles: quarks, leptons, mesons, and baryons. You’ll learn how they interact through the strong, weak, and electromagnetic forces. You’ll also learn about symmetry, quantum numbers, and how the Standard Model helps us make sense of particle behaviour. From Feynman diagrams to resonance phenomena, you’ll use real mathematical tools that physicists use in research.

This module connects theoretical physics with experimental techniques and real-world applications, from energy production to medical imaging to particle accelerators.
