    The decay Λ0b→J/ψ Λ is observed in 110 pb-1 of pp̄ collisions taken at √s=1.8 TeV. These data are used to measure a Λ0b mass of 5621±4(stat)±3(syst) MeV/c2, and a mass difference between the Λ0b and the B0 of 340±5(stat)±1(syst) MeV/c2. The production cross-section times branching fraction for the decay Λ0b→J/ψ Λ relative to that for the decay B0→J/ψ K0S has been measured to be 0.27±0.12(stat)±0.05(syst).
