Enhanced Schiff and magnetic quadrupole moments in deformed nuclei and their connection to the search for axion dark matter

NUCLEAR STRUCTURE ¹⁵³Eu, ¹⁵³Sm, ¹⁵⁵Gd, ^161,163Dy, ¹⁶⁵Er, ^221,223Fr, ²²³Rn, ^225,227Ac, ²²⁵Ra, ²²⁹Th, ²²⁹Pa, ^233,235U, ²³⁷Np, ²³⁹Pu; calculated collective Schiff moments for octupole deformed nuclei which contain a low lying energy doublet to the ground state with identical spin and opposing parity, energy shift in solids induced by nuclear Schiff moment and magnetic quadrupole moment. Discussed candidate crystals, which could be used for axion dark matter search, which may exhibit an enhanced energy shift due to the nuclear Schiff moment octupole mechanism.
