A new determination of the $\Lambda^{0}$ mean life

From 6582 kinematically-reconstructed Lambda /sup 0/ to p pi decays observed in an optical spark chamber, the Lambda /sup 0/ lifetime was evaluated to be tau /sub Lambda /=(2.69+or-0.05)*10/sup -10/ sec. This value is a factor of 1.067+or-0.020 higher than the present world average. (5 refs).
