Abstract
The prospect of creation of the energy accumulator based on the 186mRe nuclear isomer (a half-life of 2 × 105 yr) requires the choice of conditions of natural rhenium irradiation by reactor neutrons for production of a large amount of the isomer. The known calculations of dependence of the isomeric ratio at formation of 186Re nuclei in ground and isomeric states show insignificant difference between isomer production efficiencies by thermal neutrons and in the core of a reactor. This conclusion has been earlier confirmed experimentally with an accuracy up to 20%. A method for a more accurate experimental test of results of the isomeric ratio calculation has been proposed in this work.
