We have investigated the inclusive production of ..gamma.., K/sup 0//sub S/, ..lambda../sup 0/, and Lambda-bar/sup 0/ in 100-GeV/c p-barp interactions in the 30-in. hydrogen bubble chamber at Fermilab. We present various inclusive distributions and compare them with corresponding distributions in 100-GeV/c pp interactions and lower-energy p-barp interactions. We find some evidence for ..sigma.. (1385) production but none for K* (890) production. We find evidence for a nonzero ..lambda../sup 0/ polarization of -0.45 +- 0.21.
