**Module description**

Nuclear particles are discussed and the stability of nuclei related to radio-active decay processes. Scattering of particles by nuclei is treated in relation to models for nuclear interaction processes and for nuclear matter. The structural properties of nuclei are related to the nuclear shell model. Nuclear fission and fusion, and the generation of nuclear energy, are described. The different species of hadrons (strongly-interacting particles), with their main properties, are introduced, with relation to the quark model. The leptons (weakly-interacting particles, including neutrinos) are related to the heavy bosons, and the fundamental forces of nature explained using Feynman diagrams. Particle detection devices and (cyclic) particle accelerators are introduced, and recent experiments to investigate the structure of the proton and to discover the top quark are described.

**Learning outcomes**

After taking this module students should be able to:

- understand the structure of nuclei
- appreciate why some nuclei are stable and others decay
- understand at a qualitative level the salient properties of elementary particles
- distinguish between real and virtual particles
- appreciate the experimental evidence underlying the model of quarks and leptons
