The complex has been formed in a supersonic expansion and excited by a laser, two electronic states were observed very deep (>5000 cm.) and showing strikingly different behaviour. The A state is not oberved in fluorescence but dissociates into Hg(.P.) and NH3, while the other state,B fl

From Five-Fold to Crystalline Symmetry in Large Clusters,size, this structure is no longer able to grow while keeping its symmetry. This is observed in argon clusters, the diffraction patterns of which show icosahedral features up to about 750 atoms i.e. 5.5 icosahedral layers, but anomalous features beyond this size. Such anomalous features tend to give

Rather, a finite system may display either a finite range of temperature and energy throughout which the different “phases” coexist, or a range in which the system appears to be a slush, with properties intermediate between those of
