PbF electric field dependent g-factor & Zeeman shifts

POSTER

Abstract

The electric field dependent g-factor and the electron electric dipole moment (eEDM)-induced Stark splittings for the lowest rotational levels of 207PbF and 208PbF are calculated. Observed and calculated Zeeman shifts for 207PbF are found to be in very good agreement [1], as has earlier been shown for 208PbF [2]. These findings further substantiate previous proposals that the 207PbF hyperfine sublevels provide a promising system for the eEDM search and related experiments [3,4]. Progress on a global fit for the 4 stable PbF isotopologues including high vibrational state data will also be presented.
