Abstract

States in the neutron-deficient Te-110,Te-112 isotopes have been populated following Ni-58 + Ni-58, Ni-60 reactions. Gamma-ray coincidence data were acquired with the Eurogam spectrometer in conjunction with the Daresbury recoil separator and with the Chalk River 8pi 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 Te-112 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.
