| Zusammenfassung | By measuring the nuclear magnetic spin precession frequency of polarized 129Xe and ³He, we previously reported [Phys. Rev. Lett. 123, 143003(2019)] a new upper limit on the 129Xe atomic electric dipole moment (EDM).Here, we propose a new evaluation method called global phase fitting (GPF) for analyzing the continuous phase development of ³He-129Xe comagnetometer oscillation. The Cramer-Rao Lower Bound on the 129Xe EDM for the GPF method is theoretically derived and verified with Monte-Carlo studies. Applying the GPF to the same data set used for our previous analysis leads to a consistent result with smaller statistical uncertainty. By optimizing the analysis parameters and adding data that could not be analyzed with the previous method, we obtained the result of dA(129Xe) =1.08±3.13(stat) ±1.83(syst)×10-28ecm. The updated null result can be interpreted as anew upper limit of dA(129Xe) (7.4×10-28ecm at the 95% C.L., almost a factor of 2smaller than our preceding result and roughly a magnitude lower than the result of 2001.
