Description

Precision atomic spectroscopy experiments for Be isotopes have been carried out at the prototype universal slow RI-beam (SLOWRI) setup at RIKEN. Radioactive Be ions produced at 1 GeV were decelerated and thermlized in an RF-carpet ion guide. The thermalized ions were transferred to an ion trap where laser cooling was used to reduce the ion energy to the order of 1 μeV. Laser microwave double resonance spectroscopy was performed for the hyperfine structure measurements of trapped and laser cooled 7Be+ and 11Be+ ions. Measurements of the S1/2→P1/2,P3/2 transition frequencies of 7,9,10,11Be+ ions are also in progress. These results are briefly discussed. Future prospects for expanding the capability of SLOWRI is also discussed.
