| 英文摘要 | concerted elimination pathway leading to br-2(+) and c2h4+ from 1,2-dibromoethane molecule has been investigated in 800 nm femtosecond laser field by dc-slice imaging technology. the kinetic energy release and angular distributions of br-2(+) and c2h4+ demonstrate that br-2(+) results from the two-body coulomb explosion of the doubly charged parent ion. ab initio calculations show that the doubly charged precursor overcomes a small energy barrier (0.18 ev) and then dissociates into br-2(+) and c2h4+ through a synchronous concerted elimination mechanism. moreover, the relative yield of the br-2(+) channel is obtained, and it remains about 3.4% when the laser intensity exceeds 1.0 x 10(14) w/cm(2).
