Double-quantum photoelectron emission from perylene and naphthacene crystal has been studied. Action spectra and time profiles of the photoemission indicate that, below 3.2 eV, photoemission occurs by fusion of two singlet excitons in perylene and by photoionization of singlet exciton in naphthacene

โฆ Synopsis
The energy distribution CUWES (EDC's) of the photoelectrons emitted from nap~t~acc~e (Clgff 12) and pcryfcnc (C2oFIl2) crystals were measured using the rare 83s resonance emission lines (He 21.22 eV, Ne 16.85 and 16.67 eV and Ar 11.83 and 11.62 ev). The peaks in the higher kinetic energy rgicns agree we11 with the pesks ob:ainccI from moIccuhr photoclcctron spectroscopy studies if constant energy shifts xc aaumed. In the lower kinetic encrg) regions, !lowcver, fixed kinetic energy peaks xc found which r\re independent of the incident photon energies.
