Overview

Nuclear Forces and Reactions

Pre/co-requisites

Unit title Unit code Requirement type Description
Nuclear Physics PHYS40322 Pre-Requisite Compulsory

Aims

To introduce the main features of the forces between nucleons and reactions between
nuclei, and to link nuclear physics to other areas of physics.

Learning outcomes

This course unit detail provides the framework for delivery in 20/21 and may be subject to change due to any additional Covid-19 impact.  Please see Blackboard / course unit related emails for any further updates

On completion successful students will be able to:
1. describe the mean features of the forces between protons and neutrons, and their relation to the underlying forces between quarks.
2. use cross sections and phase shifts to describe quantum mechanical scattering processes.
3. show how simple models can explain the main features of nuclear reactions.
4. explain how specific nuclear reactions are responsible for the formation of the elements.
