| 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 X 1016 ions cm-2. The residual gas pressure in the irradiation chamber was 1. 3 X 10 -4 Pa 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. |
