Séminaire S. Sunil Kumar (23 février 2010)

Indian Institute of Technology Madras, Chennai, India

The dissociation dynamics of a molecule may often be dramatically affected by electron correlations. In the presentation, I will talk about an experimental work, in which the importance of electron correlations in determining the dissociation dynamics of sulphur hexafluoride (SF6) was examined using time-of-flight momentum imaging spectrometry. SF6 was irradiated by two different photon energies well below and well above the sulphur 2p threshold in SF6. This choice of photon energies allowed us to study the effect of electron correlations resulting from the inner-shell ionization. The presentation will focus on the study on two different fragmentation channels of interest and on a sequence of fragmentation channels in which triply ionized SF6 dissociates into three singly charged fragments. A remarkable feature of the study is the use of a novel method employed to determine the role of neutral fragments in the dissociation sequence of SF63+.
