Abstract

The Gammasphere spectrometer, in conjunction with the Microball charged-particle array, was used to investigate high-spin states in Te112 via Ni58(Ni58, 4pγ) 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 1832 yield a transition quadrupole moment of 4.0±0.5eb, which corresponds to a quadrupole deformation ɛ2=0.26±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, 2pγ) reaction. A value of 3.0±0.5eb was found in the spin range 1624, which corresponds to a quadrupole deformation ɛ2=0.19±0.03. Cranked Nilsson-Strutinsky calculations are used to interpret the results.
