Abstract

We report the investigation on three-body fragmentation of CF43+ induced by 1 keV electron collision utilizing an ion momentum spectrometer. With the help of coincidence measurement for three fragment ions, the channel CF43+-> F++CF2++F+ is identified. By employing Dalitz plot and Newton diagram, a sequential path-way and a concerted pathway are uncovered, which are further separated by momentum correlation of two F+ ions. We find that the CF43+ fragmentation prefers a sequential pathway CF43+ -> F++CF32+ -> F++ F++CF2+.
