DESCRIPTION – summary of the module content (100 words)

This module is an Independent Study version of PHY3052. It is taken by students remote from Exeter, e.g. at Stage 3 of F304, who are therefore unable to attend traditional lectures and tutorials.

This module is an introduction to nuclear and particle physics delivered as a series of lectures and integrated self-study packs presenting topics as a series of keynote areas forming the foundations of the subject. This is a core module for all Physics programmes and is supported by Stage 3 tutorials and problems classes.

MODULE AIMS – intentions of the module

Investigations of the atomic nucleus and, of the fundamental forces that determine nuclear structure, offer fascinating insights into the nature of the physical world. The tools for probing these systems are high-energy particle accelerators and, more recently, colliding-beam systems. This module, aims to give students a broad overview of the subject matter, and encouragement to seek further information.

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

On successful completion of this module you should be able to:

Module Specific Skills and Knowledge:

describe the key properties of the atomic nucleus and explain these properties with the aid of an underlying theoretical framework;

describe the basic weak interaction processes and the significant experiments that elucidate the nature of these;
describe the quark model and be able to construct the quark composition of particles;
explain the significance of symmetry to the multiplet structure of elementary particles;
solve problems on topics included in the syllabus;

Discipline Specific Skills and Knowledge:

identify significant applications which make use of nuclear physics, and explain the role of nuclear physics in these applications;

Personal and Key Transferable / Employment Skills and Knowledge:

give qualitative descriptions of complicated theories;
reason logically within a set of given constraints;
identify significant strands in a mass of confusing data.
