Half-life of the 15/2⁺ state of ¹³⁵I A test of E2 seniority relations

NUCLEAR REACTIONS ²³⁵U(n, F)¹³⁵I, E=cold neutrons at PF1B facility and high-flux reactor of the ILL-Grenoble; measured prompt Eγ, Iγ, half-life of (15/2+) state in ¹³⁵I by γγ(t) using EXILL-FATIMA γ-detector array of Clover Ge and LaBr₃ detectors. ¹³⁵I; deduced levels, B(E2), configuration, E2 seniority relations between B(E2) values in neighboring nuclei.

NUCLEAR STRUCTURE ¹³⁴Te, ¹³⁵I; calculated levels, J, π, B(E2) by large-scale shell-model calculations; deduced large two-body component of the E2 operator, whereas small energy shifts due to the three-body component of the effective interaction.
