  • PH-113 Essential Skills for Physicists

    This module facilitates the learning transition and adaptions required for study at University. Learning methodologies will be introduced and key aspects of developing an understanding of available resources for self-study will be presented. The module¿s approach is via student engagement in a series of intensive, staff-led activities giving them the skills required to be educated effectively in Physics at an undergraduate level.

  • PH-306 Atomic Physics I

    This course describes the application of quantum mechanics to atomic structure, together with the implications for spectroscopy. The electronic structure of hydrogen (including spin, fine structure and hyperfine structure), helium and alkali metals will be discussed from first principles in quantum mechanics. The effect on energy levels of applied magnetic fields (Zeeman effect) is calculated in perturbation theory. Practical examples of spectroscopy are briefly described.
