Abstract

The glass transition in both single- and polycrystalline C60 at about 90 K was studied using high-resolution capacitance dilatometry. This glass transition is most pronounced in samples which also have a sharp orientational-ordering transition at T≤260 K. The kinetics of the relaxation processes near the glass transition were obtained by fitting the experimental results with a simple glass- transition model. The relaxation time obeys an Arrhenius-behavior with Ea ≤ 288 meV over more than 10 orders of magnitude when including other published data.
