AbstractHigh-spin states of Sr-84 are populated through the reaction Zn-70 (O-18, 4n) Sr-84 at the beam energy of 75 MeV. The measurements of excitation functions, gamma-gamma coincidences, directional correlations of oriented states (DCO) ratios and gamma-transition intensities are performed using eight anticompton HPGe detectors and one planar HPGe detector. Based on the experimental results, we establish a new level scheme of Sr-84, in which 12 new states and nearly 30 new gamma-transitions are identified in the present work. The positive-parity yrast band is extended to spin I-pi = 24(+), while one negative-parity band is extended to spin I-pi = 19(-) and it is found that the even-spin and odd-spin members in high-spin states show the nature of signature staggering. The deformation of Sr-84 is studied by calculating the total-Routhian-surfaces (TRS) of positive-parity yrast states in the cranked shell model formalism.
