    Notes: 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 1s ionization region whereas B+ is more intense than F+ at the F 1s→2a2″ excitation. Two partial cross sections σ|| and σ⊥ for A1′→E′ parallel and A1′→A2″ perpendicular transitions are obtained from the angular distribution measurement of energetic photoions and the symmetries of some F 1s core excited states are confirmed. The dissociation dynamics of the F 1s−12a2″ core excited state are discussed in detail. © 1997 American Institute of Physics.

    Notes: Angle resolved photoelectron and photoion spectroscopy has been used to investigate the e′ shape resonance just above the B 1s ionization threshold of BF3. The B 1s photoelectron asymmetry parameter β is ∼0 in the vicinity of the peak of the shape resonance and increases with increase in photon energy, illustrating good agreement with a theoretical prediction. From the angular distribution measurement of energetic F+ fragments following B 1s photoionization, we have decomposed the photoionization cross section into two components σe′ and σa2″ for the B 1s→e′ parallel and B 1s→a2″ perpendicular transitions and confirmed that the shape resonance is in the e′ symmetry component. © 1997 American Institute of Physics.
