Abstract
Parity conservation was tested for the LAMBDA deg production processes: pi /sup -/ + N yields LAMBDA deg + anything, where the nucleon N is in a carbon nucleus. Approximately 120,000 pictures were taken of a propane bubble chamber exposed to a pi /sup -/ beam of 2.0 Bev/c momentum. On the basis of 486 events, of which all but 23 were identified without ambiguity as A deg , no indication of parity nonconservation was found. This result rests on the fact that the average LAMBDA deg polarization P in the production plane was found to be consistent with the value zero within the statistical error. The values found for two components of P in the production plane are: -0.08 plus or minus 0.12 and 0.00 plus or minus 0.12, using the value plus or minus 0.63 for alpha , the asymmetry parameter.
