摘要：

We have performed momentum-dependent electron energy-loss studies of magnetically aligned bundles of single wall carbon nanotubes. Our experiment directly shows the anisotropy in the electron diffraction and C1s absorption spectra. We do not observe any anisotropy for the low energy interband transitions related to the van Hove singularities in the nanotube density of states although we observe a strong anisotropy for the pi plasmon.
