Summary on Grant Application Form |
|
A unique apparatus has been developed which combines the coincident detection of both ionic and neutral fragments following the photoexcitation of a cluster ion. The detection system is coupled to a supersonic nozzle that generates clusters which are then ionised and mass-selected using a high resolution tandem mass spectrometer. Following photoexcitation, the kinetic energies of neutral fragments are measured using a time-of-flight (tof) device an ions are energy analysed using a combination of tof and electrostatic deflection. The relationship between scattering pattern and angle polarisation of the incident laser radiation plays an important part in the analysis of results. The objective is to use coincident detection and covariance mapping to provide a quantitative picture of the complex decay dynamics exhibited by both pure and mixed rare gas cluster ions. In the former, eg Arn+, we will examine the energetics associated with individual decay pathways as determined through the selection and identification of a particular ion fragment. Of interest will be the role of spin-orbit coupling in determining the outcome of photoexcitation. In mixed cluster ions, eg Kr+ or Ar+, with coincident neutrals.
