The isomeric ratios in neutron capture reactions, induced by thermal, resonant and mixed thermal-resonant neutrons on ¹¹⁴Cd and ¹¹⁶Cd nuclei have been measured by the activation method using off-line gamma spectroscopy. The data analysis and necessary corrections as the self-absorption and summing cascade effects were made in gamma rays radioactivity measurements to improve the precision of the isomeric ratio determination. The results were discussed and compared with those in the existing literature, which can contribute as additional data to the nuclear data banks and used for theoretical calculations in nuclear reaction models as well as for nuclear applications.

在¹¹⁴ Cd 和¹¹⁶ Cd 核上由热、共振和混合热共振中子引起的中子俘获反应中的异构体比率已通过使用离线伽马能谱的活化方法测量。在伽马射线放射性测量中进行了数据分析和必要的校正，如自吸收和叠加级联效应，以提高异构比测定的精度。对结果进行了讨论并与现有文献中的结果进行了比较，这些文献可以作为附加数据提供给核数据库，并用于核反应模型的理论计算以及核应用。
