Thesis. Submitted to Chicago Univ., Ill. Dept. of Physics. The differential cross section in the reaction π^-p→ K°Λ°, π^-p→ K°Σ° was measured at incident beam momenta of 3, 4 and 6 GeV/c and at momentum transfers to t approximates - 2.0. The polarization of Λ° was also measured at 5 GeV/c using the parity violating decay Λ° → pπ^-. Wire spark chambers with magnetostrictive readout, scintillators, and Cerenkov counters were used and most of the calculations were performed on-line with an EMR6050 computer. Due to the experimental method the results have much smaller error than previous bubble chamber measurements.
