Abstract

Excited levels of Te-128 to 3.3 in MeV excitation have been studied using gamma-ray spectroscopy following inelastic scattering of accelerator-produced neutrons. Spectroscopic information, including transition energies, level spins, E2/M1 multipole-mixing ratios, and gamma-ray branching ratios, was determined from gamma-ray excitation functions measured from E-n = 2.15-3.33 MeV in 90-keV increments, gamma-ray angular distributions measured at E-n = 2.2, 2.8, and 3.3 MeV, and gamma gamma coincidences measured at E-n = 3.6 MeV. Lifetimes of levels in Te-128 were deduced using Doppler-shift attenuation techniques. Absolute transition probabilities were determined for many levels and compared to interacting boson model and particle-core coupling model calculations to identify few particle and collective structures; states exhibiting the decay characteristics expected for two-phonon, mixed-symmetry, and quadrupole-octupole coupled states are identified.
