摘要
用14MeV中子轰击天然锇靶,取道^(192)Os(n,α)反应生成^(189)W。利用改进的锇蒸馏装置蒸馏OsO_4,完成锇与反应产物的分离;通过四苯砷铼沉淀除去铼。使用HPGe探测器测量了分离的钨样品的γ射线谱,该γ射线谱显示钨样品中杂质元素的去污是令人满意的。
^(189)W was produced via the reaction ^(192)Os(n,α) in 14 MeV neutron bombardment of nature osmium. OsO_4 was dis-tilled over by distilling in order to separation of osmium from the reaction products. Rhenium was then removed as tetrapheny-larsonium perrhenate. The γ ray spectrum of the separated tungsten fraction was measured using an HPGe detector. The γ rayspectrum shows decontamination of the impurity elements in the tungsten fraction is quite satisfactory.
