Measurement and analysis of the isomeric cross section ratios for the Tc 94 nucleus

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.
