We study the effects of surface reconstruction on the absorption spectra and optical gaps of hydrogen-terminated silicon clusters. The spectra and gaps are computed using an ab initio method based on the linear response theory within the time-dependent local-density approximation (TDLDA). Our calcul
We present experiments in which a beam of neutti #i,O), clusters are scsttered at various solid surfaces. ft is shown that at cluster sizes ~r~spond~ng to NS 300 cluster cations, anions and electrons appear in the scattered Bow. As Nincreases the current of cluster cations f, and anions I\_ becomes
A sinple model is proposed for molecular dissociation probabilities in impulsive cotlisions with surf&cs. Dissociation is assumed to foliow rotational excitation high enough to break the molecule. The model WIS tested against exact classical simulations for 12, Liz colliding with smooth surfaces.
