N2 - Ultrafast isomerization of acetylene cations ([HC=CH]⊃+) in the low-lying excited AΣg+2 state, populated by the absorption of extreme ultraviolet (XUV) photons (38 eV), has been observed at the Free Electron Laser in Hamburg, (FLASH). Recording coincident fragments C⊃++CH2+ as a function of time between XUV-pump and -probe pulses, generated by a split-mirror device, we find an isomerization time of 52±15fs in a kinetic energy release (KER) window of 5.8<KER<8eV, providing clear evidence for the existence of a fast, nonradiative decay channel.
