- The authors review their neutron diffraction studies of the intercalation of the rare gases into the interstices of C₆₀ at pressures ranging from 0 to 6 kbar, primarily at room temperature, but also at other temperatures. Room temperature compressibilities of C₆₀ for both the face-centered-cubic and simple-cubic phases using Ar, which does not intercalate, as the pressure medium are in excellent agreement with the earlier work of David et al, while the values for He and Ne are slightly smaller than those using Ar. The rates of intercalation and release of Ne, at a number of different temperatures, have been measured and show that, at a given temperature, intercalation is much slower than release. Structural refinements of the Ne intercalated C₆₀ have been carried out for room temperature samples at many different pressures. These data suggest that Ne only intercalates into the octahedral hole and that the occupancy increases smoothly with pressure. Intercalated materials are important technologically for their use as catalysts, waste storage media, solid-state batteries, molecular sieves, gettering materials, and in many other applications. Sometimes, intercalation endows the new material with remarkable properties.
