The ..lambda.. anti ..lambda.. system produced in the reaction ..pi../sup -/p ..-->.. n..lambda.. anti ..lambda.. at 6.0 and 7.0 GeV/c has been studied utilizing the ANL 1.5 m Streamer Chamber Facility. The trigger requires an all neutral final state and the detection of at least two charged particles in a downstream hodoscope. A 400,000 photograph exposure yielded 284 unweighted n..lambda.. anti ..lambda.. events. The cross section for the reaction is 0.51 + 0.22 ..mu..b at 6.0 GeV/c and 1.21 + .23 ..mu..b at 7.0 GeV/c. There is an indication of a possible baryonium state with a mass and width of approximately 2430 MeV and 60 MeV respectively. The structure appears as a 2.5-standard deviation effect in the mass spectrum, and there are correlated effects in the ..lambda.. and anti ..lambda.. polarizations, the distribution of the Jackson angle, and the /t/ distribution.
