We report on an isomer yield ratio study of biologically important $^{94}\mathrm{Tc}$ following the fusion of the $^{9}\mathrm{Be}+^{89}\mathrm{Y}$ system, carried out using the offline $\ensuremath{\gamma}$-ray spectroscopy in continuation to the online activation method. The incident beam energies considered are above the Coulomb barrier for the present paper. The platypus model in conjunction with a potential model calculation was employed to analyze the data. An agreement in the order of magnitude between the experimental data and the theoretical predictions has been achieved by applying a phenomenological approach. The approach was further tested with isomer yield ratios of $^{94}\mathrm{Tc}$ formed through $^{3}\mathrm{He}+^{93}\mathrm{Nb}$ reactions. Possible factors that relate to the isomer yield ratios are also presented.

Tc94核异构体横截面比的测量和分析

我们报告了在 $^{9}\mathrm{Be}+^{89}\mathrm{Y}$ 系统融合后对生物学上重要的 $^{94}\mathrm{Tc}$ 的异构体产率比研究，使用离线 $\ensuremath{\gamma}$ 射线光谱继续在线激活方法。本文考虑的入射光束能量高于库仑势垒。鸭嘴兽模型结合潜在模型计算被用来分析数据。通过应用现象学方法，已经实现了实验数据和理论预测之间的数量级一致。该方法进一步测试了通过 $^{3}\mathrm{He}+^{93}\mathrm{Nb}$ 反应形成的异构体产率比 $^{94}\mathrm{Tc}$。还介绍了与异构体产率相关的可能因素。
