Abstract

Polymerization of C₆₀ thin films by 7-MeV C 2+ ion irradiation is studied with Raman spectroscopy and X-ray diffraction (XRD). Raman analysis reveals that polymerization of the C₆₀ molecules that have survived destruction by ion bombardment proceeds with further irradiation; after irradiation with 1×10 16 /cm 2 , most of the surviving molecules have been polymerized. XRD analysis shows that reflection angles of 111 and 222 in an fcc crystal of C₆₀ shift to higher angles with the increasing ion fluence. This is due to the contraction of the intermolecular distance induced by the polymerization and the contraction amounts to 4% after the irradiation with 1×10 16 /cm 2 .
