Exciton annihilation processes involving biexcitonic interactions are known to efficiently ionize molecular and semiconductor crystals and large molecular clusters. We present the first spectroscopic evidence for biexcitonic two-photon ionization of small molecular clusters. In this case the process resembles resonant multiphoton autoionization of two-electron atoms.
