Abstract

Values of the isomer ratios for nuclei 87m,gY, as products of the photonuclear reactions 90Zr(g, 2np) 87m,gY, 91Zr(g, 3np)87m,gY, were obtained using Bremsstrahlung of the LU-40 electron linear accelerator with endpoint energy 90 MeV for irradiation of targets. Energy resolution of electron beam was about 1% and mean electron current was near 5 μA. Method of the induced activity was used to obtain experimental isomer ratios.
