A mass spectrometric investigation of the photofragmentation behavior of mixed clusters composed of C70 molecules and iridium atoms (C70)mIrx (m=2, 3; x>2) reveals that coalesced fullerenes C138−2n and C206−2n (n=0, 1, 2,…) are the predominant

Both neutral and charged (C 60 ) n clusters were heated to temperatures at which they evaporated molecules. Particularly stable clusters resisted evaporation and manifested themselves as enhanced peaks in the mass spectra. At 490 K, the set of enhanc

We present results of first principles calculations of the geometric and electronic structure of the networked iron fullerene C59Fe. This heterofullerene is obtained from C60 by replacing a C atom with a Fe atom and relaxing self-consistently the str

One of the most appealing aspects of cluster science while it was still in its infancy was the simplicity of the objects studied. More recently, cluster beam experimentalists have begun to direct their interest to more complex condensates which might

Si-doped heterofullerenes C59Si and C58Si2, obtained from C60 by replacing one and two C atoms with Si atoms, are investigated via first principles calculations. Static geometry optimizations show that structural deformations occur in the vicinity of
