Abstract
The results of measurements and calculations of isomeric ratios for the ^{87m,g}Y nuclei, as products of the ^{90}Zr(γ,2np)^{87m,g}Y and ^{91}Zr(γ,3np)^{87m,g} photonuclear reactions, are
presented in this work. The samples were irradiated by using bremsstrahlung of the electron linear accelerator LEA40 with endpoint energy E_{γmax} = 84 MeV. The method of the induced
activity measurement by a HPGedetector was used to obtain experimental isomer ratios. The results were compared with calculations in the TALYS 1.0 code using statistical and pre
equilibrium modeling approaches.
