Origin of the low energy resonance in the double photoionization of pyrene and coronene, and its absence in the double photoionization of corannulene

Ralf Wehlitz, David L. Huber

The low energy resonance in the double photoionization of the aromatic hydrocarbons pyrene (C${}_{16}$H${}_{10}$) and coronene (C${}_{24}$H${}_{12}$) is investigated theoretically using an…
