Levels ofTe124from the Decay of 4.2-DayI124

The population of levels of ${}_{}{}^{124}{}_{}{}^{}\mathrm{Te}$ from the decay of 4.2-day ${}_{}{}^{124}{}_{}{}^{}\mathrm{I}$ has been investigated by studying the ${}_{}{}^{124}{}_{}{}^{}\mathrm{I}$ $\gamma$ rays with a Ge(Li) Compton suppression spectrometer and with NaI(Tl)-Ge(Li) coincidence systems. Seventy-two $\gamma$ rays were identified as originating from ${}_{}{}^{124}{}_{}{}^{}\mathrm{I}$, and 62 of them were assigned to 24 levels of ${}_{}{}^{124}{}_{}{}^{}\mathrm{Te}$. The levels populated from ${}_{}{}^{124}{}_{}{}^{}\mathrm{I}$ decay are compared to the levels of ${}_{}{}^{124}{}_{}{}^{}\mathrm{Te}$ populated from the decay of the ${}_{}{}^{124}{}_{}{}^{}\mathrm{Sb}$ isomers. The nature of the levels is discussed in the framework of the quasiparticle and spherical vibrational models.
