Calculation of the (T,P)-odd Electric Dipole Moment of Thallium
Abstract
Parity and time invariance violating electric dipole moment of 205Tl is calculated using the relativistic Hartree-Fock and configuration interaction methods and the many-body perturbation theory. Contributions from the interaction of the electron electric dipole moments with internal electric field and scalar-pseudoscalar electron-nucleon (T,P)-odd interaction are considered. The results are d(205 Tl)=-582(20) de or d(205 Tl)=-7.0(2)× 10-18CSP e cm. Interpretation of the measurements are discussed. The results of similar calculations for 133Cs are d(133 Cs)=124(4) de or d(133 Cs)=0.76(2)× 10-18CSP e cm.
