CERN-ISOLDE中钚质量范围内分子离子的源内和陷阱内形成
摘要：从铀碳化物靶材中提取的镅核插入CERN-ISOLDE设施上采用同位素在线分离技术得到了包含放射性分子离子束的研究。该研究探究了两种分子束的产生方法：从离子源中提取分子离子束以及在充气射频四极离子阱中从分质离子束中形成分子离子。报道了U$^+$，UO$\_{1-3}^+$，UC$\_{1-3}^+$，UF$\_{1-4}^+$，UF$\_{1,2}$O$\_{1,2}^+$的离子电流。还识别了亚稳的钽和铀氟化物分子离子。观察到从U$^+$，UF$\_{1,2}^+$的分质离子束中与残留气体形成UO$\_{1-3}^+$，U(OH)$\_{1-3}^+$，UC$\_{1-3}^+$，UF$\_{1,2}$O$\_{1,2}^+$的现象。给出了捕获时间对分子形成的影响。
