Re-appraisal of the P, T-odd interaction constant W_d in YbF: Relativistic configuration interaction approach

摘要

Restricted active space (RAS) configuration interaction (CI) approach is employed to compute the P, T-odd interaction constant W_d for the ground (~2∑_(1/2)) state of YbF molecule. The present estimate of W_d = -1.164 × 10~(25) Hz/e-cm is expected to provide a reliable limit on the electron's electric dipole moment (EDM), d_e.
