【摘要】 文章介绍了³⁶Ar（n,p）³⁶C1反应截面测量中的浓缩³⁶Ar 气体样品和供加速器质谱技术（AMS）测定³⁶C1样品的制备。所制备的³⁶Ar 样品的体积约0.4 ml,重量约0.5 mg,所含³⁶Ar 原子数目的相对误差约为（3—4）‰。对³⁶Ar 气中的反应产物³⁶C1核素进行了回收并制备成 AgC1供 AMS 测量使用。更多还原

【Abstract】 The preparation of enriched ³⁶Ar gas samples and ³⁶Cl samples for the use in the AMS measurement of ³⁶Ar（n,p） ³⁶Cl reaction cross section was described. The ³⁶At samples prepared had the volumes of about 0. 4ml and the weights of about 0.5mg. The uncertainty in atomic numbers of ³⁶Ar was （0. 3 ～0.4）%. The reaction product, ³⁶Cl, in the ³⁶Ar was collected and the AgCl samples were prepared.更多还原
