Abstract

Few-photon induced ultrafast dynamics in acetylene (C₂H ₂) leading to several dissociation channels - deprotonation (H ⁺+C₂H⁺ and H⁺+C₂H ²⁺), symmetric break-up (CH⁺+CH⁺) and isomerization (C⁺+CH₂⁺) - were investigated employing the (XUV; extreme ultra-violet)-pump-(XUV; extreme ultra-violet)-probe scheme at the free-electron laser in Hamburg, combined with multi-hit coincidence detection. The kinetic energy releases and fragment-ion momentum distributions for various decay channels are presented. The C ⁺+CH₂⁺ and H⁺+C₂H ²⁺ channels reveal clear signatures of ultrafast molecular mechanisms, demonstrating potential applications of our pump-probe technique to complex systems in order to study a large variety of ultrafast phenomena in the XUV regime.
