Introduction,tionist, concentrating on the properties of individual atoms and molecules. In the 1930’s, this line led to nuclear physics and then to particle physics. The other stream has emphasized the properties of very, very many atoms or molecules together, so many that the aggregates they make can be treate

Theoretical Concepts,imental conditions. Their existence can not be understood and explained using conventional valence concepts. Clusters are characterized by a large number of surface atoms and this represents a substantial difference with respect to crystals. Consequently, clusters are different from both molecules a

Experimental Methods,cussion. Most of the chapter will deal with the various sources used to produce clusters. Despite intense developments in the last years, this is still a difficult enterprise. New types of cluster sources are constantly developed. Some examples only will be discussed here. Problems with detectors fo

Across the Periodic Table,n connection with that alkali clusters are also considered as prototypes of metals clusters. However the applicability of methods based on concepts well proven in solid state physics can start to be questionable when a cluster is very small. Going from atom to the bulk the question is from what clus

Cluster properties are dicussed for clusters composed of alkali metals, semiconductors, transition metals, carbon, oxides and halides of alkali metals, rare gases, and neutral molecules. The book contains several well-integrated treatments, all prepared by experts. Each contribut

Experimental Methods,r cluster ions are treated in Section 3.2. Electron diffraction from a cluster beam is discussed in Section 3.3. Methods to produce neutral mass selected clusters are reviewed in Section 3.4. Section 3.5 contains a brief overview of different types of mass spectrometers. Methods for optical and electron spectroscopy are discussed in 3.6 to 3.8.
