✦ Synopsis


Optical conductivity tensor and electron energy loss function for individual single-wall carbon nanotubes (SWCNT) of arbitrary chirality are found. The reported two types of results obtained in the TEM measurements on the isolated SWCNT of the same diameter are interpreted. The di erence in plasmon excitation probabilities is shown to be related to the di erent numbers of allowed interband transitions in the chiral and achiral tubes, while the peak position shift is to be attributed to the interrelationship between the parities of the electronic states of the armchair tubes and the polarization of the perturbing ÿeld.

Co-evaporation of carbon, in the presence of helium with some other element as catalyst, yields interesting new molecules of the fullerene family which have tubular morphologies with a crosssection at the nanoscale but lengths at the macroscale. In particular, using Ni or Co based mixtures as cataly
