“…Nominal (KH) 3 C 60 has been reported to reveal three thermal desorption peaks at 373, 725 and 1024 K. The peaks at 725 and 1024 K are ascribed to the desorption of hydrogen included as hydride ion. The nominal (KH) 3 C 60 used for the measurement has been determined to have a composition of K 3 C 60 H 1.1 from the integrated amount of desorbed hydrogen [9]. Caesium-doped fullerene is found to absorb hydrogen to form Cs 6 C 60 H 8.0 .…”

Positron-annihilation / Alkali-metal-fulleride / Thermal-desorption / Raman-shiftSummary. Hydrogen-doped alkali-metal fullerides were studied by means of mass-analyzed thermal desorption and positron annihilation. The hydrogen desorption spectra reveal the inclusion of hydrogen in the fullerides as two types of components; one weakly adsorbed and the other strongly bound, probably as hydride ion. The positron lifetime spectra demonstrate that hydrogen-doping to alkali-metal fullerides increases a concentration of higher-order vacancy-type defects, through which more than 50% injected positrons decay with a lifetime of 0.42-0.71 ns.
