Light emissions accompanying molecular ionization found by a new triple coincidence technique

A new electron-photon-ion(s) coincidence technique has enabled the discovery of new emissions from photoionization of N2, NO, CO, CO2, CS2, OCS, N2O, SO2 and CF4. For N2O, we see evidence of fluorescence from the doubly charged ion to a dissociative state. For CS2, an emission is found in coincidence with the stable doubly charged ion.
