Laser induced fluorine elimination from CF<sub>3</sub><sup>+</sup>.
ORAL
Abstract
The fragmentation of CF3+ molecular ions is studied by probing a fast (few keV) CF3+ ion beam with intense femtosecond laser pulses (790- and 395-nm center wavelength). The charged and neutral molecular fragments are detected employing coincidence three-dimensional momentum imaging. We investigate the competition between two fluorine elimination channels, CF2+ + F and CF22+ + F, with and without ionization. We also observe double fluorine elimination channels, CF+ + F + F and CF2+ + F + F, amongst other three-body breakup channels. Curiously, we note significant contributions of the charge-asymmetric fragmentation channel, CF22+ + F, in addition to the charge-symmetric breakup channel, CF2+ + F+.
