【 摘 要 】

Coincidence momentum imaging is a powerful method to study molecular structure and dynamics. Here, we used the Coulomb explosion imaging method together with synchrotron radiation and ultrafast laser pulses in order to distinguish between geometric isomers of C2H2Br2, C2H2Cl2, and difluoroiodobenzene and to investigate their fragmentation dynamics following both strong-field and inner-shell photoionization.
