Abstract
High-spin states have been studied in neutron-deficient Te-109(52), populat ed through the Ni-58(Ni-58,alpha 2pn) reaction at 250 MeV. The GAMMASPHERE gamma-ray spectrometer has been used in conjunction with the MICROBALL char ged-particle detector and 15 neutron detectors in order to select weakly po pulated evaporation residues. New band structures have been established in Te-109. Measured B(E1) strengths are discussed in terms of octupole correla tions in this mass region. In addition, possible noncollective oblate state s have been identified.
