Research activities:
Atomic Molecular & Optical Physics Division
Our interests lie both in collisions and in spectroscopy, largely experimental but with a significant theoretical contribution. Topics of current interest include:

• non-adiabatic collision calculations, including charge transfer and mutual neutralization; ion mobility studies; cold atom collisions;
• comprehensive characterisation of atomic excited states produced by electron impact;
• spectroscopy of doubly-charged molecular ions investigated using a fast ion-beam-laser spectrometer;
• electron angular distributions in photo double ionization of atoms and molecules;
• cross sections for technological plasmas;
• atomic and molecular ionisation in femtosecond spectroscopy.

Surface Physics Division
Our research encompasses studies of the dynamics of the interaction of atomic and molecular species with surfaces and of surface modification and erosion using ion beams. Topics of current interest include:

• scattering of 100eV - 5keV ionised and neutral molecular beams from surfaces under glancing incidence conditions (application of high resolution time of flight and position and time sensitive coincidence techniques; H₂, H₂⁺, H₃⁺ fragmentation, charge capture, vibrational & rotational excitation, isotope effects)
• scattering of 100eV - 5keV ionised and neutral atomic beams from surfaces under glancing incidence conditions (application of high resolution time of flight techniques; structure scattering, penetration, identification of energy loss channels)
• surface erosion at defect structures, surface topography evolution under low energy ion beam irradiation (application of ion beams, STM and AFM)
