Research Interests

• Atomic Collisions, Molecular Fragmentation (Experiments)
• momentum spectroscopy of doubly charged molecular ions (formed by electron-impact )
• photoionisation and fragmentation of molecules (using the Indus-1 synchrotron )
• ion molecule collisions -- fragmentation dynamics of multiply charged molecular ions (using the Pelletron accelerator at IUAC )
• Photochemistry of of heteregenous phases
  • Generation of carbon clusters by laser ablation and cathode sputtering
  • TOF mass spectrometric detection
  • UV photoionisation/excitation of mixed clusters (Planned )
• Auger Electron spectroscopy : instrumentation for planetary missions
