The lifetimes of nine low-lying excited states in ${}_{}{}^{111}{}_{}{}^{}\mathrm{In}$ have been measured with the Doppler-shift attenuation method in the ${}_{}{}^{111}{}_{}{}^{}\mathrm{Cd}$(p,nγ) reaction. A comparison of experimental quantities with predictions based on the interacting boson-fermion model unravels the states due to the coupling of a ${\mathit{g}}_{9/2}$ proton hole to the quadrupole vibrations of the core. © 1996 The American Physical Society.
