Abstract
The lifetime of the ${2}^{+}$ and ${9}^{\ensuremath{-}}, {11}^{\ensuremath{-}}, {13}^{\ensuremath{-}}, {15}^{\ensuremath{-}}$ states in the neutron-deficient $^{110}\mathrm{Te}$ was measured for the first time using the recoil distance Doppler shift technique. The reported value of the reduced transition probability $B(E2;{0}_{g.s}^{+}\ensuremath{\rightarrow}{2}^{+})=4.3(8)\ifmmode\times\else\texttimes\fi{}{10}^{3}\phantom{\rule{4pt}{0ex}}{e}^{2}f{m}^{4}$ supports the systematic for even-mass Te isotopes and was interpreted in the framework of the large-scale shell model and cranked shell model calculations. The measured reduced transition probabilities in the negative-parity yrast band revealed the upward trend towards the high spins. The enhanced collectivity is discussed in terms of the tilted axis cranking approach and the symmetry configuration mixing method with the Gogny D1S interaction.
