The nuclear shape studies are done for different quasiproton bands in ${}^{179}\mathrm{Re}$ nucleus through lifetime measurement using recoil distance Doppler shift technique. The deformation driving property of the low $K$, $h_{9∕2}\left[541\right]1∕2^{-}$ intruder band and the stretching property of the high $K$, $d_{5∕2}\left[402\right]5∕2^{+}$ and $h_{11∕2}\left[514\right]9∕2^{-}$ bands are discussed. The average quadrupole moment obtained from these measurements for the $h_{9∕2}$ configuration $\left(Q_t\sim 6.5e\mathrm{b}\right)$ is found to be about $16\%$ higher than the average quadrupole moment $\left(Q_t\sim 5.6e\mathrm{b}\right)$ for the $d_{5∕2}$ and the $h_{11∕2}$ configurations. The higher value of quadrupole moment for the low $K=1∕2$, $h_{9∕2}$ band as compared to the high $K=9∕2$, $h_{11∕2}$, and $K=5∕2$, $d_{5∕2}$ bands indicates its deformation driving property. The cranked Hartree-Fock-Bogoliubov and the microscopic Hartree-Fock calculations are done for these bands and are compared with the experimental observations.
