Abstract

The coulombic fission of binary metal clusters composed of lithium and calcium atoms has been studied by time-of-flight mass spectrometry following multi-photon ionization. The determined appearance sizes are compatible with predictions of a simple model which assumes a liquid droplet picture for all but the very small clusters involved. Electronic shell effects on the fission process are discussed.
