Abstract：
A new form solid Carbon has been synthesized consisting of a hexagonal close packing of a26 molecules under energetic C₂₆ ion 2.4 MeV bombardment of ultra high molecular weight polyethylene. The beam current was about 150 mA and the total dose was 1×10¹⁶ ions cm^－2. The residual gas pressure in the irradiation chamber was 1.3×10^－4Pa during bombardment High-resolu-tion transmission electron microscopy, electron diffraction, and time-of-flight mass spectroscopy studies of the molecular packing confirm that the C₂₆ molecules have the Caged fullerene structure.
