On the Possibility of Observing Stimulated De-Excitation of Nuclear Isomer 186mRe in a High-Current Z-Pinch Plasma at the ANGARA-5-1 Setup

In this paper, we consider an experimental procedure for searching for the stimulation of de-excitation of nuclear isomer (SDNI) of 186 m Re (the isomer spontaneous half-life is T 1/2 = 2 × 10 5 yr) in a high-current Z-pinch plasma. On the basis of the recently obtained results of observing SDNI for 186 m Re in a laser plasma, the possibility of observing SDNI for 186 m Re in a Z-pinch plasma with an electron temperature of ~1 keV at the Angara-5-1 setup is shown. The design of a liner, a set of metal wires with the 186 m Re isomer whose electric explosion produces a Z-pinch, the method for introducing the 186 m Re isomer into the liner, and the method for detecting SDNI for 186 m Re in a Z-pinch plasma are discussed.
