The polarization of quasifree hyperons produced by the (+K+) reaction on C12 and on the deuteron was measured for the first time. The asymmetry of pions from weak decay of the hyperon was used to determine the polarization. The polarization for the deuterium target was found to be consistent with that for the elementary n(+,K+) reaction. The polarization of the produced by the quasifree process from C12 is consistent with that for the elementary reaction, which demonstrates that the spin characteristics of the elementary reaction are not modified by the nuclear medium.
