Popis: A new method is described for effective mass measurement in the decays: x→ γ + γ ; x→e + +e − ; x→ π 0 + γ ; x→ π 0 + π 0 ; etc. with a two-channel system of jointly operating spark chambers and Cerenkov gamma-spectrometers. The system is calibrated for the decays: η 0 → γ + γ . The ΔM / M resolution has been obtained to be ±10%.
