摘要：
Based on U-238 photofission experiments with the bremsstrahlung photons, the isomeric yield ratios were measured for Nb-95 and Xe-133 nuclei at the end-point energy E-e = 12.5 MeV, and Xe-135 nuclei at E-e = 12.0 MeV. Experimental values of isomeric yield ratios were obtained taking into account the contribution from beta-decay of isobaric nuclei in yields of investigated isotopes. Average angular momenta of investigated fission fragments were determined using the statistical model of decay.
