High-spin excitations of the odd-odd $^{88}_{37}Rb_{51}$ and $^{86}_{35}Br_{51}$ nuclei: $\pi$p_{3/2}\nu_{5/2}$ and $\pi f_{5/2}$\nud_{5/2} residual interactions

Abstract : The odd-odd 88 37Rb51 and 86 35Br51 nuclei have been produced as fission fragments in the fusion reaction 18O$ + $208Pb at 85MeV bombarding energy and studied with the Euroball IV array. Their high-spin level schemes have been built from the triple -ray coincidence data and - angular correlations have been analyzed in order to assign spin and parity values to many observed states. The proposed configurations involve proton excitations from three sub-shells located close to the Fermi levels, p 3/2 , f 5/2 , and g 9/2 , the d 5/2 neutron acting as a spectator. The residual interactions are extracted from the multiplets of states resulting from the p 3/2 d 5/2 and f 5/2 d 5/2 configurations. The empirical values of the latter are discussed and compared to those known in two similar configurations having j p = j n with l p = l n + 1 , where the role of the tensor force had been highlighted.
