β-decay scheme of ¹⁴⁰Te to ¹⁴⁰I: Suppression of Gamow-Teller transitions between the neutron h_9/2 and proton h_11/2 partner orbitals

RADIOACTIVITY ¹⁴⁰Te(β^-), (β^-n)[from ⁹Be(²³⁸U, F), E=345 MeV/nucleon using BigRIPS separator at RIBF-RIKEN]; measured Eγ, Iγ, βγ-, γγ-coin, half-life of ¹⁴⁰Te decay using EUROBALL-RIKEN Cluster Array (EURICA) for γ rays and WAS3ABi array for β and ion detection. ¹⁴⁰I; deduced levels, J, π, logft, multipolarities, configurations. Comparison with shell model and Nilsson model calculations. Systematic of Gamow-Teller strengths of 1+ states in ^136,140,142I, ^142,146Cs, ^{142,144,146,148}La, ¹⁴⁶Pr. ¹³⁹I; observed γ rays.
