| Outline of Final Research Achievements |
We have so far been discovered the transformation from neutron-irradiated highly oriented pyrolytic graphite (HOPG) to amorphous diamond. Here, we have investigated the change of the neutron-irradiated HOPG under high pressure in high temperature (HPHT) condition. At 2300℃/15GPa, we observed transformation to a polycrystalline diamond. At 1500℃/15GP, we observed the formation of compressed graphite. The structural changes are considered to originate in some effect of neutron irradiation-induced defects.
