Excited states in the doubly-${\mathrm{odd}}^{184}$Au nucleus have been studied by in-beam γ-ray spectroscopy. This nucleus was produced through the fusion-evaporation reactions ${}_{}{}^{165}{}_{}{}^{}\mathrm{Ho}$${(}^{24}$Mg, 5n), ${}_{}{}^{170}{}_{}{}^{}\mathrm{Yb}$${(}^{19}$F, 5n), and ${}_{}{}^{161}{}_{}{}^{}\mathrm{Dy}$${(}^{27}$Al, 4n). Different rotational band structures have been observed and interpreted as specific couplings of proton and neutron single-particle excitations present in neighboring odd Au and Pt nuclei. © 1996 The American Physical Society.
