Low-Frequency Nuclear Spin Maser and Search for Atomic Edm of 129Xe

We have developed a nuclear spin maser in which highly polarized nuclei of the noble gas isotope ¹²⁹Xe oscillate at the low frequency of 34 Hz. The system is advantageous for detecting a small frequency shift of the nuclear spin precession. We are thus planning to apply this system to the search for an atomic electric dipole moment of ¹²⁹Xe. We here report the development of the system and its performance.
