Abstract
High resolution transmission electron microscopy and electron energy l oss spectroscopy are used to investigate plasmon losses of aluminum na nospheres and carbon nanotubes with high spatial resolution. We observ e that some features of the spectra depend on the size of the particle s. The suitability of a dielectric theory model to interpret the spect ra is tested in the case of Al spheres. The model permits the identifi cation of the observed peaks and reproduces the size dependent fetures . A similar model is applied to calculate excitation probabilities for carbon nanotubes.
