\begin{document}$^{177}{\rm Re}$\end{document} nucleus. For this study, the \begin{document}$^{165}{\rm{Ho}}$\end{document} (\begin{document}$^{16}{\rm{O}}$\end{document}, 4n)\begin{document}$^{177}{\rm{Re}}$\end{document} reaction at a beam energy of 84 MeV was used. Lifetimes of four lowest levels in the \begin{document}$\pi i_{13/2}[660]1/2^+$\end{document} band and four levels in the \begin{document}$\pi d_{5/2}[402]5/2^+$\end{document} (α = –1/2) band were measured. The extracted transition quadrupole moments for the \begin{document}$\pi i_{13/2}$\end{document} intruder band showed a sharp increase with increasing level spin, indicating a significant shape transition in the nucleus. The average transitional quadrupole moment (\begin{document}$Q_t$\end{document}), a measure of deformation, for the \begin{document}$\pi i_{13/2}$\end{document} band was significantly larger (\begin{document}$Q_t$\end{document} ~ 8.7 (6) eb) compared with the \begin{document}$\pi d_{5/2}$\end{document} (\begin{document}$Q_t$\end{document} ~ 6.3 (5) eb) band. To interpret the observed shape changes in the two bands, the experimental transition probabilities for these bands were compared with the results obtained from Projected Shell Model (PSM) calculations."> Lifetime measurement of high spin states in non-yrast bands in <sup>177</sup>Re -
