The dielectric tensor components of anthracene derived from energy loss experiments
Energy loss spectra of anthracene single crystals corresponding to the dielectric tensor elements ɛxx, ɛyy and ɛzz were measured with 60 keV electrons, after having fixed the main axes of the dielectric tensor corresponding to ɛxx and ɛzz. The real and imaginary parts of the dielectric tensor elements are derived from the loss functions by a Kramers-Kronig-analysis.The results are compared with those obtained by other autors and with measurements on graphite.
