DESCRIPTION - summary of the module content

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.

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)

A student who has passed this module should be able to:

Module Specific Skills and Knowledge:

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

2. identify sequences of particles as energy excitations of a ground state;

3. identify the quantum numbers that distinguish these sequences and use their conservation to analyse production processes;

4. state the relevant conservation laws and use them in analysing meson decays;

5. describe the basic weak interaction processes and the significant experiments that elucidate the nature of these;

6. describe the quark model and be able to construct the quark composition of particles;

7. explain the significance of symmetry to the multiplet structure of elementary particles;

8. solve problems on topics included in the syllabus;

Discipline Specific Skills and Knowledge:

9. 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:

10. give qualitative descriptions of complicated theories;

11. reason logically within a set of given constraints;

12. identify significant strands in a mass of confusing data.

RE-ASSESSMENT NOTES

An original assessment that is based on both examination and coursework, tests, etc., is considered as a single element for the purpose of referral; i.e., the referred mark is based on the referred examination only, discounting all previous marks. In the event that the mark for a referred assessment is lower than that of the original assessment, the original higher mark will be retained.

Physics Modules with PHY Codes

Referred examinations will only be available in PHY3064, PHYM004 and those other modules for which the original assessment includes an examination component - this information is given in individual module descriptors.
