Abstract
Shape coexistence has been established in several nuclei in the Z=50 region of the chart of nuclides, but tellurium has thus far not been definitively characterized. In an attempt to characterize the structure of 124Te, a measurement of the 123Te(n,γ) reaction was made using FIPPS, the Fission Prompt Product γ-ray Spectrometer, at the Institut Laue-Langevin in Grenoble, France. A very high statistics data set was obtained, with on the order of 108 counts in the 2+1→ 0+0 transition. γ-γ coincidence data were analyzed. Particular interest was given to the 1647 keV excited 0+ state, as a potential intruder state. B(E2) values were calculated for transitions from an elevated 2+ state that directly feeds this suspected 0+ intruder state.
