摘要

The results of studying the Λ(Λ-bar) system produced in the reaction π~-(p, C) → Λ(Λ-bar)n at a π~-- meson energy of 40 GeV are reported. Experimental data (～2300 events) were obtained on the ITEP 6-meter spectrometer with a beam of the IHEP U-70 accelerator. The invariant-mass spectra for the events dominated by the singlet or triplet Λ(Λ-bar) states were found to differ considerably from each other. The data give evidence for the existence of bumps of the Λ(Λ-bar) system in the mass regions near 2.3, 2.5 and 2.8 GeV.
