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.
