2Abstract
We recently studied the spin manipulation of 1.85 GeV/c vertically polarized deuterons stored in the COSY cooler synchrotron. We adiabatically swept an rf dipole's frequency through an rf-induced spin resonance and observed its effect on the deuterons' vector and tensor polarizations. After optimizing the resonance crossing rate and maximizing the rf dipole's voltage, we measured spin-flip efficiencies of 97 +/- 1% and 98.5 +/- 0.3% in two separate runs. We also confirmed at higher energy the striking behavior of the spin-1 tensor polarization recently found at IUCF
