Abstract
Excited levels of Te to 3.3 in MeV excitation have been studied using -ray spectroscopy following inelastic scattering of accelerator-produced neutrons. Spectroscopic information, including transition energies, level spins, 2/1 multipole-mixing ratios, and -ray branching ratios, was determined from -ray excitation functions measured from –3.33 MeV in 90-keV increments, -ray angular distributions measured at , 2.8, and 3.3 MeV, and coincidences measured at MeV. Lifetimes of levels in Te 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.
