%X Stored beams of polarized protons, electrons, or deuterons can be spin flipped by sweeping an rf dipole's or solenoid's frequency through an rf spin resonance. Fitting such data to the modified Froissart-Stora equation's spin resonance strength epsilon(FS) gave very large deviations from the *epsilon(Bdl) obtained from each rf magnet's integral B(rms)dl. We recently varied an rf dipole's frequency sweep range Delta f, and the momentum spread Delta p/p and betatron tune v(y) of stored 1.85 GeV/c polarized deuterons. We found a sharp constructive interference when v(y) was near an intrinsic spin resonance. Moreover, over large Delta f and Delta p/p ranges, epsilon(FS) was about 7 times smaller than the predicted *epsilon(Bdl).
