Research Interests:

1.Structure of very unstable nuclei with a large excess of proton number to that of neutron, or vice versa:
   Our unique methods utilizing lasers to control the spin orientation of unstable nuclei and/or atoms are successful in measurements with high sensitivity and high precision for nuclei far from the stability line. We have performed a series of experiments at TRIUMF in Canada and at RIBF in RIKEN.

2.Structure of high-spin isomers (long-lived excited states) and search for exotic nuclear shape.
   A highly sensitive system is used consisting of an in-flight beam separator for fusion products, particle detectors with large solid angle and Ge-detector array for gamma-ray detection. We are searching for new isomers as clues to yet undiscovered exotic deformed states. The experiments are performed at RCNP, Osaka University.
