Abstract A method is presented to eliminate quantitatively the decay time of the radioactive source and all systematic errors caused by the instability of the associated electronics. The essential part of this procedure is a versatile method to measure the random coincidences together with the sum of true and random coincidences under the same experimental conditions for both quantities. The proposed method is applied toγ-γ-directional correlation measurements with a five detector apparatus. The construction and function of the device is illustrated. Test measurements with60Co prove the usefulness of the method and the capability of the apparatus. The investigation of twoγ-γ-cascades in the decay of124Sb gives the following values for the coefficients of the correlation function 1,69-0,603 MeV-cascade:A 2=−0,065±0,003A 4=+0,001±0,005 2,09-0,603 MeV-cascade:A 2=−0,056±0,008A 4=+ 0,006±0,008
