✦ Synopsis

A preparative high-performance liquid chromatography was examined for the isolation of higher fullerenes from CSz extracts of the carbon soot produced by arc heating of graphite in inert atmosphere. At least eight all-carbon compounds CW, CT,,, C,,, CT8, Cs2, Csl, Cgo and Cq6 were confirmed as a "stable fullerene". Cg2 and C96 arc new members of liullerene family which have not been reported so far. The presence of stable Cnl seems to he closely related with the recent success of macroscopic quantities of _.

produciion of La& reported by Smalley's group.

Ultraviolet photoelectron spectra of higher fullerenes CT8 and Cgg are measured with a synchrotron radiation light source. The spectral intensity oscillates and the peak positions shift, when the incident photon energy is changed. The hv=20 eV spectrum of CT8 resembles that of CT6, which suggests th
