【摘要】 对天然锇同位素进行了离心分离。选择OsO4作为工作介质,以单机分离实验结果证实了γij=γ0ΔAij关系式,拟合出实际的γ0。在此基础上通过四台级联分离实验得到了192Os丰度大于99%的OsO4。更多还原

【Abstract】 Osmium isotopes in the natural isotopic mixture are separation by gas centrifuge technology. OsO₄ is chosen as the process gas. The relationship γ_ij=γ₀^ΔA_ij is verified by experiments using a single centrifuge, and the real value of γ₀ is obtained by fitting. Based on this, a four-stage cascade is degigned to separate ¹⁹²Os. The results show that the abundance of ¹⁹²Os is more than 99%.更多还原
