Abstract

States in the neutron-deficient Te110,112 isotopes have been populated following Ni58+58,60Ni reactions. Gamma-ray coincidence data were acquired with the Eurogam spectrometer in conjunction with the Daresbury recoil separator and with the Chalk River 8spectrometer. Although the low lying yrast states are not collective in these nuclei, a long regular cascade of transitions, indicating collective behavior, was found in Te112 extending to high spin. This structure is interpreted in terms of a deformed 4-particle 2-hole 02+ state coupled to rotationally aligned quasiparticles, and represents the first example of a rotational intruder band in the tellurium isotopes.
