Photoexcitation of radioactive ⁹⁹Tc was studied by irradiation with 15-50 MeV bremsstrahlung. The integral cross sections of the ⁹⁹Tc(γ, γ′)^99mTc reaction and the reference ¹¹⁵In(γ, γ′)^115mIn reaction were found to be nearly constant as (5.8 ± 1.0) × 10^-27 cm² MeV and (9.3 ± 0.4) × 10^-27 cm² MeV, respectivel in the given energy range. The large second increase of the cross section described in earlier reports was observed neither for ¹¹⁵In nor for ⁹⁹Tc.
