Lifetimes and shape-coexisting states of ⁹⁹Zr

NUCLEAR REACTIONS ²³⁵U(n, F), E=cold neutrons from high-flux reactor of the Institut Laue-Langevin; measured Eγ, Iγ, level half-lives by γγ(t) using EXILL-FATIMA Ge and LaBr₃(Ce) detector array for fast-timing technique. ⁹⁹Zr; deduced levels, J, π, B(E2), B(M1), Q(transition), β₂, configuration, kinematic moment of inertia for ν3/2[451] band. Systematics of kinematic moments of inertia of ν3/2[411] bands in ^99,101,103Zr, ⁹⁷Sr. Comparison with theoretical calculations using IBFM-1 model, and with previous experimental results.
