At the VEPP-4M collider the record accuracy of 10−6 of an absolute beam energy calibration was achieved with the resonant depolarization technique in the energy range including the J/ψ, ψ(2S), ψ(3770) resonances as well as the τ - lepton production threshold. This report discusses the methods, equipment and the results.
