Lifetimes of the Metastable $6\mathrm{d}{}^2{\mathrm{D}}_{5/2}$ and $6\mathrm{d}{}^2{\mathrm{D}}_{3/2}$ States of Ra${}^{+}$

Haoran Li, Huaxu Dan, Mingyu Fan +9

We report lifetime measurements of the metastable $6\mathrm{d}{}^2{\mathrm{D}}_{5/2}$ and $6\mathrm{d}{}^2{\mathrm{D}}_{3/2}$ states of Ra${}^{+}$. The measured lifetimes, ${\tau }_5=$…
