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 ^212,213,214Ra⁺ ions. The isotope shift of the 6 ²D_3/2 - 7 ²P_1/2 and 6 ²D_3/2 - 7 ²P_3/2 transitions and the hyperfine structure constant of the 7 ²S_1/2 and 6 ²D_3/2 states in ²¹³Ra⁺ 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 ²D_5/2 state was measured by optical shelving.
