Abstract：
In order to assign γ-ray multipolarity, a method of ADO ratios deduced from coincidence data has been described. The factors affecting the reliability of the ADO ratios have been discussed using an experimental detector configuration. The multipolarities for known γ-rays deduced by the ADO method are consistent with the previous results obtained from γ-ray angular distribution and DCO ratio measurements. This consistence proves that the ADO method is reliable. The advantages of the ADO method over the traditional DCO ratio measurement have been discussed.
