Abstract
The hyperfine splittings of ground state have been measured precisely by laser-microwave double resonance spectroscopy for trapped and laser cooled beryllium ions. The ions were produced at relativistic energies and subsequently slowed down and trapped at mK temperatures. The magnetic hyperfine structure constant of was determined to be from the measurements of the field independent transition. This measurement provides essential data for the study of the distribution of the halo neutron in the single neutron halo nucleus through the Bohr-Weisskopf effect.
