Research Interests:

1. 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.

2. Structure of nuclei far from the beta-stability line and evolution of structure as a function of isospin.
   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. The experiments are performed at TRIUMF in Canada.
