The structure of ${}^{194}\mathrm{Ir}$ is investigated via ($n,\gamma ),(n,e^{-}),(d,p)$, and ($\overrightarrow{d},\alpha$) spectroscopy. The use of different methods leads to an almost complete level scheme up to high excitation energies including γ-decay and spin-parity assignments. A reanalysis of the formerly published ($n,\gamma$) data was triggered by our new ($d,p$) and ($\overrightarrow{d},\alpha$) transfer reactions. The experimental level scheme is compared to predictions using extended supersymmetry. Herein, the classification of states was done according to quantum numbers, excitation energies, and ($\overrightarrow{d},\alpha$) transfer strengths. A one-to-one correspondence in excitation energies was obtained for the 23 lowest lying theoretical states with similar structures for the experimental and calculated level schemes. The two-nucleon transfer strengths show remarkable agreement. A Nilsson classification is discussed as well.
