Development of a new method for polarizing unstable nuclei

为了研究中等质量丰中子核的核矩，我们研制了质子自旋极化系统和极化转移系统。该系统将与来自CYRIC在线RF离子导向同位素分离器的慢RI束一起使用。该系统工作在真空、室温和低磁场强度下，其中核自旋极化迄今尚未实现。虽然目前还没有实现不稳定核的自旋极化，但随着自旋极化系统的进一步发展，该系统将在不久的将来完成。

In order to study nuclear moments of neutron-rich nuclei in medium mass region, we have developed a proton spin polarizing system and polarization transfer system. This system will be used with slow RI beam from the RF ion guide isotope separator on-line at CYRIC. The system thus works in vacuum, room temperature and low magnetic field strength, in which nuclear spin polarization has not been realized so far. Although a spin polarization of unstable nuclei has not been achieved in the term, the system will be completed in the near future, together with further development of spin polarizing system.
