Abstract
We have measured the asymmetric emission of protons from the nonmesonic decay of polarized produced by the reaction. is an -shell hypernucleus and its polarization is due to the . One expects to obtain direct information on the elementary weak process. The asymmetry parameter has been determined to be . The implication of the result is discussed.
