Abstract
The analyzing power in inclusive and production has been measured with a 200 GeV/c transversely polarized antiproton beam over a wide range and at moderate . The asymmetry increases with increasing from zero to large positive values for 's, and decreases from zero to large negative values for 's. A threshold for the onset of the asymmetry is observed about , below which is essentially zero and above which increases (decreases) with for 's ( 's) in the covered range.
