为降低瞬发γ射线法在测量重裂变核（n ，x nγ）截面中的康普顿坪和本底水平，尝试采用符合方法来分析数据。在中国原子能科学研究院600 kV 高压倍加器上用两个 Clover 探测器直接测量56 Fe（n ，xnγ）5个能点的反应截面，然后采用符合技术分析数据，计算1238.3 keV γ射线截面。此结果与直接方法计算的截面结果基本一致，从而验证了符合测量方法的有效性。

When measuring (n ,xnγ) partial γ-ray cross section of heavy fissionable nuclei , the technique of coincidence measurement was applied to depress Compton platform and background of energy spectrum .Five energy points of 56 Fe(n ,xnγ) cross sections were measured directly by two Clover detectors on 600 kV Cockcroff-Walton accelerator in CIAE ,and then the offline data analysis at 1 238.3 keV was performed by using the coincidence technique .The result is approximately the same as direct measurement result and the availability of the technique of coincidence measurement is proved .
