First observation of candidate chiral doublet bands in Z=37 Rb isotopes

NUCLEAR REACTIONS ⁷⁶Ge(¹¹B, 3n)⁸⁴Rb, E=36 MeV; measured Eγ, Iγ, γγ-coin, γγ(θ)(ADO ratios) using an array of six Compton-suppressed HPGe detectors and one clover detector at the HI-13 tandem accelerator of CIAE-Beijing. ⁸⁴Rb; deduced high-spin levels, J, π, B(M1)/B(E2) ratios, chiral doublet bands, configurations, staggering parameters. Comparison with triaxial relativistic mean-field theory and triaxial particle-rotor model calculations. Systematics of positive-parity yrast states in ^{76,78,80,82,84}Rb.
