We study the e+e-→ΛΛ̅ γ, ΛΣ̅ 0γ, Σ0Σ̅ 0γ processes using 230 fb-1 of integrated luminosity collected by the BABAR detector at e+e- center-of-mass energy of 10.58 GeV. From the analysis of the baryon-antibaryon mass spectra the cross sections for e+e-→ΛΛ̅ , ΛΣ̅ 0, Σ0Σ̅ 0 are measured in the dibaryon mass range from threshold up to 3 GeV/c2. The ratio of electric and magnetic form factors, |GE/GM|, is measured for e+e-→ΛΛ̅ , and limits on the relative phase between Λ form factors are obtained. We also measure the J/ψ→ΛΛ̅ , Σ0Σ̅ 0, and ψ(2S)→ΛΛ̅ branching fractions.
