摘要:High spin states of Sr-84 were populated through the reaction Zn-70(O-18, 4n)Sr-84 at 75 MeV beam energy. Measurement of excitation function, gamma-gamma coincidences, directional correlation from oriented state (DCO) ratios and gamma-transition intensities were performed using eight anticompton HPGe detectors and one planar HPGe detector. Based on the measured results, a new level scheme of Sr-84 was established in which 12 new states and nearly 30 new gamma-transitions were identified in the present work. The positive-parity states of the new level scheme were compared with the results from calculations in the framework of the projected shell model (PSM). One negative-parity band was extended to spin I (pi)=19(-) and it can be found that in the high spin states, the gamma-transition energies show the nature of signature staggering. The negative-parity band levels are in good agreement with deformed configuration-mixing shell model (DCM) calculations.
