Abstract

An alternative technique of coincidence between energy-selected electrons and mass- and energy-selected photoions, combined with angle-resolved photoion spectroscopy, has been applied to investigate the state-selected dissociation dynamics of the B 1s core-excited BF3 molecule. Dissociation from the spectator Auger final states both above and below the double-ionization threshold produces energetic B+ in the secondary processes of stepwise dissociation after the molecular deformation (D3h→C3v), in marked contrast to dissociation following B 1s ionization in which energetic F+ is ejected within the D3h plane of the parent BF3 molecule.
