The nucleus ${}^{185}\mathrm{Au}$ was populated using the reaction ${}^{159}\mathrm{Tb}\left({}^{30}\mathrm{Si,}4n\right)$${}^{185}\mathrm{Au}$ at $140\text{MeV}$ beam energy. Lifetimes for the $E2$ transitions in $h_{9∕2}$ and $i_{13∕2}$ bands have been measured using recoil distance method. The reduced transition probabilities $B\left(E2\right)$ and transitional quadrupole moments $Q_t$ were extracted using the measured lifetimes. Calculations of quasiparticle Routhians and total Routhian surfaces (TRS) have been performed to investigate the effect of the $\beta$- as well as the $\gamma$-driving properties of these configurations in this nucleus.
