Abstract

The unstable odd-Z, odd-N isotope ¹⁸⁶Re exists in a mid-shell deformed region of the chart of the nuclides where long-lived nuclear isomers are common. ¹⁸⁶Re (ground-state half-life T_1/2 = 3.7186 d) has an isomer with a half-life of ~2.0 x10⁵ y. The ^186mRe isomer is a candidate energy-storage medium for a radioisotope power source of military importance that would operate on the principle of isomer depletion. Data about levels and transitions above the ^186mRe isomer, absent from the adopted level scheme for ¹⁸⁶Re, are needed to identify a means of depleting the isomer. Four experiments were performed to investigate the ¹⁸⁶Re level structure, which involved three different reactions...
