Lifetimes and transition probabilities for the low-lying states in ¹³¹I and ¹³²Xe

RADIOACTIVITY ^131mTe[from ²³⁸U(α, F), E=40 MeV]; ¹³²I(β^-)[from decay of ¹³²Te formed in ²³⁸U(α, F), E=40 MeV]; measured Eγ, Iγ, γγ-coin, level half-lives by γγ(t) fast-timing method, and half-life of 1797-keV nanosecond isomer in ¹³¹I by slope method using the VENTURE array of CeBr₃ scintillators and VENUS arrays of six Compton-suppressed Clover HPGe detectors at the K-130 cyclotron facility of VECC, Kolkata. ¹³¹I, ¹³²Xe; deduced levels, J, π, configurations, B(E1), B(E2), B(E3). Systematics of E1 decays from 11/2- levels in ^{121,123,125,127,131}I, and 13/2- and 15/2- levels in ¹²⁹Sb, ^131,133I. Comparison with large-basis shell model calculations using the NUSHELLX code.

NUCLEAR STRUCTURE ¹³¹I, ¹³²Xe; calculated levels, J, π, dominant particle partitions, configurations, and level half-lives using the large-basis shell model (LBSM) with the NUSHELLX code. Comparison with experimental data.
