Abstract
The Coulomb explosion of CO2 into multicharged atomic ions is investigated following the ejection of up to 9 electrons by an intense femtosecond laser field. The identification of several fragmentation channels OZ++CZ'++OZ"+ is performed from triple ion correlation experiments. As already observed for the Coulomb explosion of N2 by a strong picosecond laser field. the measured kinetic energy releases are 50% weaker than the Coulomb repulsion energies calculated at the equilibrium internuclear distances. In addition, there is evidence for bending of the molecule during the explosion around the average linear structure. This experimental observation is tentatively assigned to bending vibrations arising from the violent laser-induced alignment of the molecule along the laser polarization direction before the explosion.Keywords
