Abstract: This paper deals with the results of isomer ratio measurements for nuclei ^110m,gIn and ^108m,gIn from photonuclear reactions ¹¹³In(γ, 3n)^110m,gIn, ¹¹⁵In(γ, 5n)^110m,gIn, ¹¹⁵In(γ, 7n)^108m,gIn. Bremsstrahlung energies varied within (34÷43) MeV for ¹¹³In(γ, 3n)^110m,gIn reaction, in energy region (43÷100) MeV for ¹¹⁵In(γ, 5n)^110m,gIn and ¹¹⁵In(γ, 7n)^108m,gIn reactions. The instrumental gamma-ray spectra of irradiated target specimen have been measured with high purity germanium semiconductor spectrometer. The isomer ratio results and dependence of isomer ratios upon maximal bremsstrahlung energies within selected range are obtained and discussed.

Keywords: isomer ratios, photonuclear reactions, neutrons, indium, TALYS.
