| الوصف: | High-spin states of 84Sr were populated through the reaction 70Zn(18O, 4n)84Sr at 75 MeV beam energy. Measurement of excitation function, gamma-gamma coincidences, directional correlation of oriented states (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 84Sr 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 results from calculations in the framework of the projected shell model (PSM). One negative-parity band was extended to spin I=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 the deformed configuration-mixing shell model (DCM) calculations. |
