Octupole correlations near ¹¹⁰Te

NUCLEAR REACTIONS ⁵⁸Ni(⁵⁸Ni, 2pα)¹¹⁰Te, E=250 MeV; measured Eγ, Iγ, γγ-coin, half-lives of levels by recoil distance Doppler-shift (RDDS) method using a plunger device and differential decay curve method (DDCM), GALILEO Ge-detector array for γ detection and EUCLIDES Si-array for particle detection and reaction channel selection at the XTU-Tandem accelerator facility of National Legnaro Laboratories. ¹¹⁰Te; deduced levels, J, π, B(E2); calculated collective wave functions in (β₂, β₃) plane for the two lowest negative parity states. Comparison with theoretical calculations using tilted axis cranking approach and the symmetry configuration mixing method with the Gogny D1S interaction. Discussed systematics of configurations, and octupole admixtures for the known bands in ¹⁰⁹Te, ¹¹⁰Te and ¹¹¹I.
