摘要：
Using the photoelectron-energy-selected photoion coincidence technique, we find that photoions of BF3 with kinetic energy larger than 4 eV are predominantly F+ in the F Is ionization region whereas Bf is more intense than F+ at the F 1s-->2a ''(2) excitation. Two partial cross sections all and sigma(perpendicular to) for A(1)'-->E' parallel and A(1)'-->A(2) '' perpendicular transitions are obtained from the angular distribution measurement of energetic photoions and the symmetries of some F Is core excited states are confirmed. The dissociation dynamics of the F 1s(-1)2a(2) '' core excited state are discussed in detail. (C) 1997 American Institute of Physics.
