Abstract
Double ionisation of mercury by 40.8 eV photons has been studied using coincidence techniques and photoelectron spectroscopy. Photoionisation at this wavelength is found to populate all energetically accessible states of the doubly charged ion. Measurement of the electron energy distribution reveals that non-resonant autoionisation contributes significantly to the formation of the 1S0 state, and unidentified structure in the photoelectron spectrum represents states involved in this indirect double ionisation process.Keywords
