Abstract: Our research group fulfilled measurements of relative output fragments activities of ²³²Th photofission by γ-quanta with boundary energies 22 MeV. As the results of experiments, in spectra activities of isomeric pairs ^117m,gIn, ^135m,gXe and feeding radionuclide were discovered. At first these researches allow to measure quantities of σ_m/σ_g for these fragments, which were found equal for ¹¹⁷In σ_m/σ_g = 1.3 ± 0.4 and for ¹³⁵Xe σ_m/σ_g = 0.66 ± 0.09. We define quantities of medium angular moments for ¹¹⁷In J = 7.5 and for ¹³⁵Xe J = 4.5.
