We performed delayed coincidence measurements for the first excited levels of ${}_{}{}^{107}{}_{}{}^{}\mathrm{Cd}$ and ${}_{}{}^{105}{}_{}{}^{}\mathrm{Cd}$ and obtained the following results: $\tau (205\mathrm{} \mathrm{keV},{}_{}{}^{107}{}_{}{}^{}\mathrm{Cd})=(1.03\mathrm{}\pm 0.05)$ ns, $\tau (321\mathrm{} \mathrm{keV},{}_{}{}^{107}{}_{}{}^{}\mathrm{Cd})\le 60$ ps, $\tau (131\mathrm{} \mathrm{keV},{}_{}{}^{105}{}_{}{}^{}\mathrm{Cd})=(2.52\mathrm{}\pm 0.15)$ ns. Experimental results are in agreement with the predictions of the intermediate coupling nuclei.
