The γ-ray transitions following the β decay of ${}_{}{}^{110}{}_{}{}^{}\mathrm{In}_{}^{\mathit{m}}{}_{}{}^{}$ (half-life 69 min) were observed using Compton-suppressed Ge detectors. The activity was produced by the ${}_{}{}^{111}{}_{}{}^{}\mathrm{Cd}$(p,2n) reaction at a bombarding energy of 18.9 MeV. Singles in multispectra mode and γγ-coincidence experiments were performed. Approximately 150 transitions were assigned to ${}_{}{}^{110}{}_{}{}^{}\mathrm{Cd}$, based on their measured half life and/or observation in coincidence with well-known lines. The ${\log }_{10}$(ft) values of nearly all observed levels were determined and an analysis of the beta-decay strength using microscopic theory was performed. The experimental data were interpreted in the framework of the interacting boson model.
