Excitation of high spin isomers in photonuclear reactions

The probabilities of high spin isomer (J ≥ 10) excitation were measured for the odd-odd isotopes 182Ta, 190Ir, 194Ir, 196Au and 206Tl in the photonuclear reactions (γ,n) and (γ,p). The activation method was used for the determination of the reaction yields of nuclei in the isomeric and ground states. The calculations of the isomer excitation probabilities on the basis of the statistical model and the comparison with the experimental data were performed
