摘要：

A crucial effect of oxygen on resistivity rho of a C60 single crystal and the temperature (160-570K) dependence of rho have been studied. The resistivity increases by a factor of 10(4) on absorption of oxygen; the estimated concentration is 4% O2 per C60. The processes of oxygen absorption and desorption are reversible. The activation energy in rho of the oxygen-free crystal is 0.26 and 0.15 eV above and below Tc=250K, respectively, which is ascribed to an impurity level.
