Electric dipole moments of actinide atoms and RaO molecule

Abstract

We have calculated the atomic electric dipole moments (EDMs) induced in 229Pa and 225Ac by their respective nuclear Schiff moments S. The results are d(229Pa)= - 9.5 10^{-17} [S/(e fm)] e cm= - 1.1 10^{-20} ηe cm; d(225Ac})=- 8.6 10^{-17} [S/(e fm)] e cm=- 0.8 10^{-21} ηe cm. EDM of 229 Pa is 3 10^4 times larger than 199Hg EDM and 40 times larger than 225Ra EDM. Possible use of actinides in solid state experiments is also discussed. The T,P-odd spin-axis interaction in RaO molecule is 500 times larger than in TlF.
