Dependence of isomeric ratios on maximum photon energy in the reactions 110Pd(γ, n)109m, g Pd and 113In(γ, n)112m, g In is studied in the energy region of bremsstrahlung 9–18 MeV with the step ΔE = 0.5 MeV. Cross sections of population of the metastable state for 109Pd and 112In in (γ, n) reactions were first obtained in the energy region under study. The obtained results are compared with the results of the calculation in the framework of the cascade-evaporation model.
