Abstract High-spin states in ⁸⁴Rb have been studied by using the ⁷⁰Zn (¹⁸O, p3n) ⁸⁴Rb reaction at a beam energy of 75MeV. The γ- γ coincidence, excitation function and ratios for directional correlation of oriented states were performed. A new level scheme was established in which the positive and negative parity bands have been extended up to 17⁺ and 17^- with excitation energy about 7MeV. The signature splitting and signature inversion of the positive parity yrast bands were observed and are discussed.
