Fragmentation dynamics of gas-phase furan followingK-shell ionization

A multicoincidence velocity-map-imaging technique was employed to study the fragmentation of inner-shell excited furan molecules for the photon energies encompassing the C and O $K$ edges. We have analyzed the kinetic energy distributions and the momentum correlations of detected ionic fragments. Comparisons of our experimental observations with predictions of a Coulomb explosion model elucidate possible fragmentation pathways.
