The existence of two decaying isomers in ${}^{184}\mathrm{Au}$ was confirmed through direct observation of the variation of decay rates with time. The ordering of the low- and high-spin isomers was verified by the decay studies. The isomers are identified as a low-spin (probably $2^{+}$) state at an energy of 69 keV with a half-life of $48\pm 1\sec$ and a high-spin (probably $5^{+}$) ground state with a half-life of $21\pm 1\sec .$
