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

Abstract

We report on an isomer yield ratio study of biologically important Tc94 following the fusion of the Be9+Y89 system, carried out using the offline γ-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 Tc94 formed through He3+Nb93 reactions. Possible factors that relate to the isomer yield ratios are also presented.
