The polarization of {xi}{sup 0} and {xi}{sup 0} hyperons produced by 800 GeV/c protons on a BeO target at a fixed targeting angle of 4.8 mrad is measured by the KTeV experiment at Fermilab. Our result of 9.7% for {xi}{sup 0} polarization shows no significant energy dependence when compared to a result obtained at 400 GeV/c production energy and at twice our targeting angle. The polarization of the {xi}{sup 0} is measured for the first time and found to be consistent with zero. We also examine the dependence of polarization on production p{sub t}.
