The temporal dependence of the metastable fractions have been measured for monomer evaporation from Ar+20, Ar+50, Ar+100, Kr+20, Kr+50, and Kr+100 ions produced by electron impact ionization of the respective neutral cluster beams. Size and temporal dependence are found to be in reasonable agreement with the predictions of the evaporative ensemble model. Small variations from the model predictions observed (in particular for the evaporation channel involving the cluster with the magic number 20) may be rationalized within this model by adjusting the appropriate parameters.

    Dust charges in a complex helium gas plasma, surrounded by cryogenic liquid, are studied experimentally. The charge is determined by frequency and equilibrium position of damped dust oscillation proposed by Tomme et al. (2000) and is found to decrease with ion temperature of the complex plasma.
