Radial E-field to Cancel the g-2 Precession in a Storage Ring: Radial E-Field: The method works well for particles with small anomalous magnetic moment a, like deuterons (a = ), etc.

Deuteron Statistical BNL:  p : 3s. Polarization Lifetime (Coherence Time) A : 0.3. The left/right asymmetry observed by the polarimeter P : The beam polarization N c : d/cycle.
