Single Photon Coulomb Explosion of Methanol, using ultrafast HHG pulses

Daniel Strasser, Hebrew University of Jerusalem, Institute of Chemistry

I will present a new method for time resolved probing of small molecular systems. 3D coincidence imaging allows disentangling rare Coulomb explosion events following double ionization by a single EUV photon from an ultrafast HHG pulse. Kinetic energy release and angularly resolved spectra are presented for several Coulomb explosion channels, including a proton migration channel producing correlated CH2+ + H2O+ cations. The measured kinetic energy release spectra are discussed in terms of the molecular structure and compared to ab-initio calculations.
