| Research Abstract |
In order to investigate the new process of diamond formation induced from the irradiation of high energy particles supported by Kaminsky’s hypothesis, chemical separates from natural organic matters in the Oklo natural nuclear reactors were used in this study. The chemical separates were further purified, and used for Raman spectroscopic observations. Raman spectra of some particles sized 50-100 μm diametersshow a clear peak at 1332 cm^<-1>, suggesting the existence of nano-sized diamonds in the particles. TEM (Transmission Electron Microscope) observation of the particles are now in progress.
