电弱放射性衰变的几种模式需要原子核和组成原子内的束缚电子之间的相互作用。因此，各个衰变的概率不仅受原子核中初始态和终态的结构影响，而且还强烈地依赖于原子电荷。适合部分或完全电离这些稀有同位素的条件自然发生在炎热、密集的天体物理环境中，但也可以在实验室中人工产生，以选择性地阻止某些放射性衰变模式。由于在高电荷态下产生和存储放射性离子所需的实验室条件，对这种情况的直接实验研究极其困难。一种新的电子束离子陷阱(EBIT)衰变装置与TRIUMF的泰坦实验一起成功地展示了这种技术，用于对高电荷态离子的放射性衰变进行光谱分析。
Several modes of electroweak radioactive decay require an interaction between the nucleus and bound electrons within the constituent atom. Thus, the probabilities of the respective decays are not only influenced by the structure of the initial and final states in the nucleus, but can also depend strongly on the atomic charge. Conditions suitable for the partial or complete ionization of these rare isotopes occur naturally in hot, dense astrophysical environments, but can also be artificially generated in the laboratory to selectively block certain radioactive decay modes. Direct experimental studies on such scenarios are extremely difficult due to the laboratory conditions required to generate and store radioactive ions at high charge states. A new electron-beam ion trap (EBIT) decay setup with the TITAN experiment at TRIUMF has successfully demonstrated such techniques for performing spectroscopy on the radioactive decay of highly charged ions.
