The first experimental evidence for the (M1 + E2) mixed character of the 9.2 keV transition in 227Th

Nuclei with enhanced Schiff moments in practical elements for atomic and molecular EDM measurements

“…Thorium: Some EDM experimental techniques work best for nuclear spin I=1/2. In addition to the well-known I=1/2 225 Ra, 227 Th likely has I=1/2 [46]. There is strong experimental and theoretical support for static octupole deformation with an identified parity double band for an I=1/2 ground state, and a large Schiff moment enhancement [8,9].…”
