About the Project
This project will investigate interactions between antimatter and ordinary matter. The work will include development of high performance computer software and calculation of potential energies of interaction for a number of key systems in antimatter research including H2 + antihydrogen atom. These potential energy surfaces (PESs) will then be used to calculate rovibrational bound states and reactive and non-reactive scattering properties. Specifically, the bound state energies and wavefunctions for these systems allow prediction and understanding of spectroscopic properties, for example energy levels and lifetimes of states. Reactive scattering results, for which current literature is sparse, give the rates of processes such as
H2 + antihydrogen atom → Pn + Ps + H
which destroy antimatter by breaking up antiatoms and eventual annihilation of the proton-antiproton and electron-positron pairs in Pn and Ps respectively.
H2 + antihydrogen atom is a high priority system for the work at CERN along with charged variants such as H2+ + antiproton. The prototype molecule-antimolecule system H2 + antihydrogen molecule will also be tackled using techniques developed for simpler systems.
The project will make use of state of the art quantum chemistry techniques to calculate reaction rates as well as highly excited vibration-rotation energy levels. Computer programs developed for this project may also be made use of by future research projects on matter-antimatter interactions involving more complex systems such as larger molecules.
The successful candidate will have or expect to have a UK Honours Degree at 2.1 (or equivalent) in Chemistry, Physics or Chemical Physics.
A strong background in physical chemistry or physics or chemical physics, including experience of: atomic structure and chemical bonding and their description by quantum mechanics; basic principles of the quantum mechanical treatments of molecular electronic, vibrational and rotational motions.
