K selection in the decay of the (ν5/2[532] (X) 3/2 [411]) 4^- isomeric state in ¹⁰²Zr

RADIOACTIVITY ¹⁰²Y(β^-)[from ⁹Be(²³⁸U, F), E=345 MeV/nucleon]; measured Eγ, Iγ, energy-time matrices in coincidence with position-correlated β decays and ¹⁰²Y ions, isomer half-life by βγγ(t) fast-timing method using BigRIPS spectrometer for ion separation, WAS3ABi system for ion and β detection and EURICA array for γ detection at RIBF-RIKEN facility. ¹⁰²Zr; deduced levels, J, π, K for the isomer, B(E1), B(M1), Weisskopf hindrance factors, configuration for the isomer. Comparison with Weisskopf hindrance factors for the transitions from the decay of 4- isomer in ¹⁰⁰Sr.
