Abstract

In the HCCH molecule, H2+ ions have been produced only at the 1s→π* excitation, suggesting that the H2+ ion formation is mediated by the core excitation. The nuclear motion in the C1s-1π* core-excited state is probed using a multiple-ion-coincidence imaging technique and the enhanced cis bending motion is found by examining the H-H correlation angle distributions. The H2+ formation is thus attributed to the cis bending motion caused in the C1s-1π* state.
