Abstract

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.
