229 Th ^+的电子桥过程

Electronic bridge process in 229Th^+

S. G. Porsev, V. V. Flambaum

摘要:

本文研究了原子电子对{229}Th ~+离子从同分异构态{229 m}Th到基态{229 g}Th的电子桥跃迁过程的影响。到目前为止,核跃迁频率的确切值是未知的;因此,我们已经开发了一种形式主义,可以用于任何核跃迁频率。我们计算了几个在实验原子光谱数据库中没有出现的高偶宇称态的位置。求出了它们的能级和g因子。

英文摘要:

We have studied the effect of atomic electrons on the nuclear transition from the isomeric {229m}Th state to the ground {229g}Th state in {229}Th+ due to the electronic bridge process. The exact value of the nuclear transition frequency is unknown so far; therefore, we have developed a formalism that can be used for any nuclear transition frequency. We have calculated positions of several high-lying even-parity states which are not presented in experimental atomic spectra databases. We have found their energy levels and g factors.
