Abstract

This work considers the possibilities of the excitation and induced decay of nuclear isomers using the promising quasi-monochromatic inverse Compton source ICS which is under development at the National Center for Physics and Mathematics. Experimentally confirmed cases of photoinduced de-excitation of isomers, such as \({}^{180m}\) Ta, \({}^{108m}\) Ag, and \({}^{68m}\) Cu, are discussed, and the obtained quantitative estimates for future photonuclear experiments, in particular on the isotopes \({}^{165}\) Ho and \({}^{199}\) Hg, are presented. It is shown that the planned parameters of the inverse Compton source, such as beam intensity and monochromaticity, will enable future high-precision measurements with a high signal-to-noise ratio. The obtained estimates of the count rate and the number of registered \(\gamma\) -quanta using an HPGe detector confirm the feasibility of performing activation experiments, as well as demonstrate the potential of the developed facility for addressing a broad range of tasks in nuclear photonics, including studies of nuclear structure and isomer decay mechanisms.
