- Abstract
The process of normal hydrogen infusion into a C60powder at 1bar and room temperature is monitored using x-ray diffraction. The effect of the intercalation on the lattice proves to be rather weak: the volume expansion upon complete saturation does not exceed 0.13%. The characteristic saturation time is found to be 320h; the corresponding diffusion coefficient amounts to (2.8±0.8)×10−14cm2/s. The integrated reflection intensity calculations for a completely saturated sample suggest that only octahedral voids are filled under the conditions of the experiment. Complete saturation has only a weak effect on the rotational subsystem of the C60fullerite: the orientational phase transition shifts by 6to7K to lower temperatures; no substantial hysteresis is noticed. The dopant shows reluctance to leave the sample under a vacuum of 10−3Torr at room temperature.
