Atom/Spin Research Group

Experimental studies are based on the use of atomic particles (electrons, positrons, ions and photons) as probes and particle spectroscopic methods. The techniques include the use of incident electron, positron and ion beams, high resolution electron energy analysers, polarised electrons and polarised atoms, electron-photon and (e,2e) angular and polarisation coincidence techniques, multichannel plate position-sensitive-detectors, high/ultra-high vacuum technology, energy analysis and detection of charged particles, photon polarimetry, thin film techniques and computer control of apparatus. Surface Science facilities of LEED, AES, XPS and EELS are used and the University service facilities in the Electron Microscopy Centre and the Crystallography Centre are available.

Enquiries from prospective students and sabbatical visitors are welcome. Representative studies are indicated in the following pages:
