Abstract

We present new evidence for the existence of a near threshold ?* shape resonance as a common feature in the photoionization of each isomer of difluorobenzene. Experimentally this is revealed by significant changes in the anisotropy of the photoelectron angular distributions (PADs) following the ionization of the optically aligned S1 state of these molecules at varying photon energies. Continuum multiple scattering X? calculations reproduce this behaviour well and allow the visualisation of the continuum shape resonances. The resonances are unusually narrow in energy (
