Abstract

The Gammasphere spectrometer, in conjunction with the Microball charged-particle array, was used to investigate high-spin states in Te112 via Ni58(Ni58, 4pI ) 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 18-32a. yield a transition quadrupole moment of 4.0Â±0.5eb, which corresponds to a quadrupole deformation É2=0.26Â±0.03; 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 Xe114, produced via the 58Ni (58Ni, 2pI ) reaction. A value of 3.0Â±0.5eb was found in the spin range 16-24a., which corresponds to a quadrupole deformation É2=0.19Â±0.03. Cranked Nilsson-Strutinsky calculations are used to interpret the results.
