Abstract
NEXAFS spectra of higher fullerenes C78, Cs4, C86, Css, C90, C92, CM and C96 were measured for the first
time. We examine these spectra in terms of the dependence of their densities of unoccupied states on the carbon number
comparing with those of C60, Cm and C7«. We also measured isomer-separated fullerenes which included carefully
separated fractions of (i) mixture of C84 with D2 and D2d symmetries, Qi) CM with C2 symmetry, and (iii) C90 with C2
symmetry. We also compared the observed spectra with the densities of unoccupied states by ab initio calculations for
C76 and C84.
