| Outline of Final Research Achievements |
We have conducted R&D of new control and observation techniques for nuclear spin polarization and gamma-ray polarization in order to develop new RI spin probe applications for nuclear physics and materials science research. First, we succeeded in measuring the nuclear electromagnetic moment of RIs including oxygen, which is desirable for use as an RI probe. In analyzing the data in collaboration with theoreticians, important results were also obtained from the theoretical study itself. As for the technical development of nuclear spin polarization production, we have conducted development of a new method utilizing nuclear spin alignment and an apparatus for the proof-of-principle of the RI atomic beam resonance. We finally have demonstrated the feasibility of highly accurate and sensitive gamma-ray polarization measurement by a new method of applying a multilayer semiconductor Compton camera for space observation to the measurement of deexcitation gamma-rays from spin-aligned nuclei.
