摘要
通过计算推断六十年代中期，美国田纳西州橡树林国家实验室在同位素分离过程中形成的亮黑色物质（PbC20）可能就是迄今发现的最早的一种填隙式金属巴基球（PbC60）。
The shiny black material, PbC20, obtained in the separation of isotopes with calutron and other methods at Oak Ridge National Laboratory,TN, USA in mid-1960's,would be lead fulleride (Pb3C60), because calculated density(3.2g/cm3)is very close to experbontal one (about 3.5g/cm3). It would be similar in structure to K3C60 or Rb3C60. Lead ions (Ph2+)were accommodated in the tetrahedral and Octahedral interstices in face-centred cubic structure of C60.
