加拿大原子能公司桥克河(Chalk River)核实验室的一个小组已报告,由激光加工第一次得到了几滴看得见的富集氘的水(重水)。研究人员伊万斯(K.Evans),麦卡宾(R.McAlpine)和爱德姆斯(H.Adams)用 CO_2 激光器的10.2微米的辐射辐照三氟代甲烷(CHF_3),这个波长优先分解含氘的分子。所生的 DF 气体与玻璃样品管的内壁反应产生D_2 O,其浓缩因子大约是2000。在劳伦斯·利弗莫尔国家实验室和联合化学物公司的激光氘浓缩的早期 A team at the Canadian Atomic Energy Agency Chalk River nuclear laboratory has reported that for the first time, a few drops of deuterium-enriched water (heavy water) were obtained by laser processing. Researchers K. Evans, R. McAlpine, and H. Adams irradiate trifluoromethanes (CHF 3) with 10.2 μm of CO 2 laser radiation, which preferentially decomposes Deuterium-containing molecules. The resulting DF gas reacts with the inner wall of the glass sample tube to produce D 2 O, with a concentration factor of about 2000.
