Abstract
We investigate the temperature dependence of the mass spectrum of the ion b eam emitted by an Au77Ge14Si9 liquid metal alloy ion source. Our results st rongly point towards the co-existence of two mechanisms for the emission of doubly-charged monomer ions: direct field evaporation and post-ionization.
