Abstract
States in the neutron-deficient isotopes have been populated following Ni reactions. Gamma-ray coincidence data were acquired with the Eurogam spectrometer in conjunction with the Daresbury recoil separator and with the Chalk River 8π 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 extending to high spin. This structure is interpreted in terms of a deformed 4-particle 2-hole state coupled to rotationally aligned quasiparticles, and represents the first example of a rotational ‘‘intruder’’ band in the tellurium isotopes.
