| Popis: | States in the neutron-deficient $^{110,112}\mathrm{Te}$ isotopes have been populated following $^{58}\mathrm{Ni}$${+}^{58,60}$Ni reactions. Gamma-ray coincidence data were acquired with the Eurogam spectrometer in conjunction with the Daresbury recoil separator and with the Chalk River 8\ensuremath{\pi} spectrometer. Although the low lying yrast states are not collective in these nuclei, a long regular cascade of transitions, indicating collective behavior, was found in $^{112}\mathrm{Te}$ extending to high spin. This structure is interpreted in terms of a deformed 4-particle 2-hole ${0}_{2}^{+}$ state coupled to rotationally aligned quasiparticles, and represents the first example of a rotational ``intruder'' band in the tellurium isotopes. |
