This laboratory conducts production and advanced uses of ion beams of short-lived nuclei. By using the nuclear beam facility which is based on the gas-jet on-line isotope separator (ISOL), systematic studies on new isotopes in the rare-earth mass region have been intensively performed and five new isotopes were identified so far in this laboratory. Precise measurements have been made to obtain nuclear data such as half-lives, Qβ-values, γ-ray energies and intensities on neutron-rich nuclides in collaboration with Nagoya and Tokushima University groups.
Advanced utilization of the nuclear beam for material science is another important research subject of this laboratory. By implanting the radioactive probe atoms from the nuclear beam facility, electromagnetic properties of a variety of materials such as zinc oxide and silver iodide have been investigated with the perturbed angular correlation (PAC) method in collaboration with a Kanazawa University group. Measurements of magnetic moments of unstable nuclei have also been carried out.
