Abstract
The Gammasphere spectrometer, in conjunction with the Microball charged-particle array, was used to investigate high-spin states in via (, ) reactions at 240 and 250 MeV. Several smooth terminating bands were established, and lifetime measurements were performed for the strongest one using the Doppler-shift attenuation method. Results obtained in the spin range yield a transition quadrupole moment of , which corresponds to a quadrupole deformation ; this value is significantly larger than the ground-state deformation of tellurium isotopes. It was also possible to extract a transition quadrupole moment for the yrast band in , produced via the Ni (Ni, ) reaction. A value of was found in the spin range , which corresponds to a quadrupole deformation . Cranked Nilsson-Strutinsky calculations are used to interpret the results.
