N2 - Excited states in Te have been identified up to spins of ∼20ℏ using the extremely weak 2p2n evaporation channel (∼0.2% of σ) from the bombardment of a backed Fe target with 243 MeV Ni ions. Channel selection and enhancement was made possible using the power of the GAMMASPHERE array to measure high-fold γ-ray coincidences and the resultant application of multiple γ-ray gating techniques. The observation in Te of two interleaved sequences of levels with assumed opposite parity connected by enhanced E1 transitions is interpreted in terms of octupole correlations. The current results for Te make it the closest nucleus to the predicted region of octupole deformation centered at N = Z = 56 yet studied to high spin.
