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

Abstract

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