新同位素²³⁵Am的产生与鉴别

摘要: 一种缺中子新同位素２３５Ａｍ通过２３８Ｐｕ（ｐ，４ｎ）２３５Ａｍ反应而产生．产物借助Ｈｅ－ｊｅｔ系统的传输，快化学分离以及γ、Ｘ射线和γ－Ｘ（γ）符合测量等得到鉴别，测得其半衰期为１５±５ｍｉｎ． A new neutron deficient isotope 235 Am was produced via 238 Pu(p,4n) 235 Am reaction. The products were identified by means of the transporting of He jet system, separating of rapid radiochemical method and measuring of γ and X rays as well as X γ coincidence. The measured half life of 235 Am is 15±5min.
