Precision hyperfine structure spectroscopy of Be isotopes at SLOWRI prototype and prospects of SLOWRI at RIKEN
نویسندگان
چکیده
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.

Measurement of hyperfine coupling constants in the 3 d 2 Dj levels of 39 K , 40 K , and 41 K by polarization quantum - beat spectroscopy
Hyperfine quantum-beat spectroscopy has been utilized in a pump-probe configuration to measure magnetic dipole (A) and electric quadrupole (B) coupling constants in the 3d D3/2 and 3d D5/2 levels of three isotopes of potassium. For many of these levels, the largest hyperfine splitting is smaller than the natural width, and so a subnatural linewidth technique is required. In the experiments, the...
متن کاملLaser cooling of Yb for isotope separation and precision hyperfine spectroscopy
The hyperfine transitions in the 399 nm S0↔ P1 line in Yb overlap with the transition in Yb. We use transverse laser cooling on this line to selectively deflect Yb atoms from a thermal beam containing both isotopes. We then use an acousto-optic modulator to span the frequency difference between the hyperfine transitions, and hence measure hyperfine structure in the P1 state. Our precise values ...

The investigation of hydrogenlike highly-charged ions is of interest for nuclear as well as for atomic physics. Measuring the ground-state hyperfine structure (HFS) splittings of these ions is a sensitive method to explore QED in extremely strong electric and magnetic fields and nuclear contributions to the electron energy. However, for a theoretical interpretation of the results it is necessar...

متن کاملHigh resolution spectroscopy of muonium
The hydrogen-like muonium atom (μe) consists of a positive muon (μ) and an electron (e−). Since it was first observed by Hughes et al. in 1960 [1], a series of precision experiments could be carried out testing bound state Quantum Electrodynamics (QED) and the nature of the muon as a point-like leptonic particle [2]. Precision values for fundamental constants could be obtained, including the fi...
