| 英文摘要 | coulomb explosion and dissociative ionization of 1,2-dibromoethane are experimentally investigated in a near-infrared (800 nm) femtosecond laser field by dc-slice imaging technology. the sliced images of the fragment ions c2h4br+, br+, c2h4+, br-2(+) and ch2br+ are obtained, and their corresponding kinetic energy releases (kers) and angular distributions are calculated. it is confirmed that the high-ker components come from coulomb explosion of 1,2-c2h4br22+, while the low-ker components come from dissociative ionization of 1,2-c2h4br2+. furthermore, the dissociation pathway leading to c2h4+ and br-2 is theoretically simulated, and the results show that the singly charged precursor overcomes an energy barrier to dissociate via an asynchronous concerted mechanism after undergoing isomerization. |
