Abstract

As an important step towards an atomic parity violation experiment in one single trapped Ra$^+$ ion, laser spectroscopy experiments were performed with on-line produced short-lived $^212,213,214$Ra$^+$ ions. The isotope shift of the $6^2$D$_3/2$-$7^2$P$_1/2$ and $6^2$D$_3/2$-$7^2$P$_3/2$ transitions and the hyperfine structure constant of the $7^2$S$_1/2$ and $6^2$D$_3/2$ states in $^213$Ra$^+$ were measured. These values provide a benchmark for the required atomic theory. A lower limit of $232(4)$ ms for the lifetime of the metastable $6^2$D$_5/2$ state was measured by optical shelving.
