56Co是标准源放射性核素，常用于探测器效率刻度，因此，在核技术应用中有重要价值。利用核科学参考文献库中的实验测量数据，对半衰期、γ发射几率等主要衰变数据进行重点分析，本文总结了评价结果，给出了整套推荐衰变数据，本数据可用于探测器高能伽马效率刻度，为其提供一个便利参考。本文数据集可在科学数据银行数据库https://doi.org/10.57760/sciencedb.j00213.00169中访问获取 (审稿阶段请通过私有访问链接查看本文数据集数据集私有访问链接https://www.scidb.cn/anonymous/bjJ1QXJl) 。56Co with γ-ray energies covering the range of 0.84~3.55MeV are important radionuclides for Ge detector calibration. The evaluated and recommended γ-ray emission probabilities were done based on the main measurements of D.C.Camp et al. and M.E.Phelps et al. before 2000. The values reported by D.C.Camp, however, were systematically lower in high energies range. In this work, using experimental measurements obtained from the Nuclear Science Reference Library, the main decay data, such as half-life and γ-ray emission probabilities, are evaluated and summarized. In the Eγ<2.5 MeV energy region, the new evaluation data in this work are in high agreement with the results of the ENSDF evaluation (Huo, J.D., 2011) and the summary report published by IAEA in 1991 (IAEA-TECDOC-619); however, in the high-energy region, i.e., in the Eγ>2.5 MeV energy region, the present work gives lower values than the other evaluation data. The deviation at 3.4 MeV is up to 2.7%. Rationality of the present evaluation and corrected method will be dependent upon new measurements, and more precise standard data are desirable. The datasets presented in this paper, including the ENDF and ENSDF format decay data files for 56Co, are openly available at https://doi.org/10.57760/sciencedb.j00213.00169 (Please use the private access link https://www.scidb.cn/anonymous/bjJ1QXJl to access the dataset during the peer review process)
