  A resonance method of measuring the electric dipole moment (EDM) of nuclei in
storage rings is described, based on two new ideas: (1) Oscillating particles'
velocities in resonance with spin precession, and (2) alternately producing two
sub-beams with different betatron tunes--one sub-beam to amplify and thus make
it easier to correct ring imperfections that produce false signals imitating
EDM signals, and the other to make the EDM measurement.
