  • High spin states of 84Rb were populated by the 70Zn (18O,p3n) reaction at 75MeV 18O beams provided by the HI-13 Tandem Accelerator of CIAE. Excitation function, gamma-gamma coincidence and DCO Ratio were measured by using 8 BGO Compton-supton-suppressed HPGe spectrometers and a planar HPGe detector. More than 40excited states and 50 γ rays were identified in the Present work. A new level scheme of 84Rb was established, in which the positive and negative bands are extended to 17+and 17－ respectively . Comparing the odd-odd Rb isotopes and N=47 isotones, the similar structure is observed in their low excited states.

Abstract: High spin states of 84Rb were populated by the 70Zn (18O,p3n) reaction at 75MeV 18O beams provided by the HI-13 Tandem Accelerator of CIAE. Excitation function, gamma-gamma coincidence and DCO Ratio were measured by using 8 BGO Compton-supton-suppressed HPGe spectrometers and a planar HPGe detector. More than 40excited states and 50 γ rays were identified in the Present work. A new level scheme of 84Rb was established, in which the positive and negative bands are extended to 17+and 17－ respectively . Comparing the odd-odd Rb isotopes and N=47 isotones, the similar structure is observed in their low excited states.
