摘要
文章介绍了^(36)Ar(n,p)^(36)C1反应截面测量中的浓缩^(36)Ar 气体样品和供加速器质谱技术(AMS)测定^(36)C1样品的制备。所制备的^(36)Ar 样品的体积约0.4 ml,重量约0.5 mg,所含^(36)Ar 原子数目的相对误差约为(3—4)‰。对^(36)Ar 气中的反应产物^(36)C1核素进行了回收并制备成 AgC1供 AMS 测量使用。
The preparation of enriched ^(36)Ar gas samples and ^(36)Cl samples for the use in the AMS measurement of ^(36)Ar(n,p) ^(36)Cl reaction cross section was described. The ^(36)At samples prepared had the volumes of about 0. 4ml and the weights of about 0.5mg. The uncertainty in atomic numbers of ^(36)Ar was (0. 3 ～0.4)%. The reaction product, ^(36)Cl, in the ^(36)Ar was collected and the AgCl samples were prepared.
