Universal Slow RI-Beam Facility at RIKEN RIBF for Laser Spectroscopy of Short-Lived Nuclei Conference Paper uri icon

abstract

  • A universal slow RI-beam facility (SLOWRI) for precision atomic spectroscopy is being built at the RIKEN Rl-beam factory. The facility will provide a wide variety of low-energy nuclear ions of all elements produced by projectile fragmentation of high-energy heavy-ion beams and thermalized by an RF-carpet ion guide. At prototype SLOWRI, radioactive Be isotope ions produced at 1 GeV were decelerated and cooled in an ion trap down to 1 jUeV by employing laser cooling. The ground state hyperfine structures of 7Be + and 11Be+ were measured accurately by laser microwave double resonance spectroscopy. Measurements of the S1/2 P1/2,P3/2 transition frequencies of 7,9,l0,llBe+ ions are jn pr0gress aiming at the study of the nuclear charge radii. Other possible experiment at SLOWRI, such as mass spectroscopy, are also discussed. 2009 American Institute of Physics.
