Abstract
Lambda<(Lambda)over bar> effective mass distributions of 2300 events from r eaction pi(-)p --> Lambda<(Lambda)over bar>n at 40 GeV measured at 6-meter spectrometer ITEP are presented. Bumps near 2.3, 2.5 and 2.8 GeV/c(2) are c learly seen. Singlet state dominates at 2.3 GeV/c(2), while state at 2.8 Ge V/c(2) is mainly triplet.
