Lifetime measurements in ⁹⁶Rb via fast-timing techniques: Investigating shape coexistence at A ∼ 100

NUCLEAR REACTIONS ²³⁵U(n, F)⁹⁶Rb, E=thermal; measured Eγ, Iγ, γγ-coin. ⁹⁶Rb; deduced T_1/2 for (3^-), (4^-), and (6^-) intraband states, B(E2), B(M1), quadrupole deformation parameter. Lifetimes measured with generalized centroid difference (GCD) method and convolution method. Comparison to the data for ⁹⁸Y. Confirmed shape coexistence in ⁹⁶Rb. Setup consisting of 1 HPGe clover detector and 4 LaBr₃:Ce fast scintillators at LOHENGRIN spectrometer (ILL).
