Abstract: Based on ²³⁸U photofission experiments with the bremsstrahlung photons, the isomeric yield ratios were measured for ⁹⁵Nb and ¹³³Xe nuclei at the end-point energy E_e = 12.5 MeV, and ¹³⁵Xe 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.

Keywords: photofission, isomeric yields ratios, mean angular momenta of fission fragments.
