Özet
Lifetimes of excited states in the yrast band of the neutron-deficient nuclide $^{166}\mathrm{W}$ have been measured utilizing the DPUNS plunger device at the target position of the JUROGAM II $\ensuremath{\gamma}$-ray spectrometer in conjunction with the RITU gas-filled separator and the GREAT focal-plane spectrometer. Excited states in $^{166}\mathrm{W}$ were populated in the $^{92}\mathrm{Mo}(^{78}\mathrm{Kr},4p$) reaction at a bombarding energy of 380 MeV. The measurements reveal a low value for the ratio of reduced transitions probabilities for the lowest-lying transitions $B(E2;\phantom{\rule{0.16em}{0ex}}{4}^{+}\phantom{\rule{0.16em}{0ex}}\ensuremath{\rightarrow}\phantom{\rule{0.16em}{0ex}}{2}^{+})/B(E2;\phantom{\rule{0.16em}{0ex}}{2}^{+}\phantom{\rule{0.16em}{0ex}}\ensuremath{\rightarrow}\phantom{\rule{0.16em}{0ex}}{0}^{+})=0.33(5)$, compared with the expected ratio for an axially deformed rotor (${B}_{4/2}$ = 1.43).
