Abstract

A new hydrofullerite was synthesized when the C₆₀ fullerite was treated under a hydrogen gas pressure of 30 kbar at 620 K for 24 h and quenched. The inelastic neutron scattering spectra of the as-prepared sample and that after annealing at 300 K showed that the as-prepared hydrofullerite consisted of C₆₀H_x molecules and interstitially dissolved molecular hydrogen. Both spectra exhibited peaks at 13 meV characteristic of polymeric fullerites.
