Material science to investigate a new process of diamond formation approached by nano-beam technology

为了研究Kaminsky假说所支持的高能粒子辐照诱导金刚石形成的新过程，本研究使用了Oklo天然核反应堆中天然有机物的化学分离物。进一步纯化化学分离物，并用于拉曼光谱观察。某些粒径为50-100 μm的颗粒的拉曼光谱在1332 cm-1处显示出明显的峰<-1>，表明颗粒中存在纳米金刚石。现在正在进行颗粒的TEM（透射电子显微镜）观察。

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.
