Abstract: New spectroscopic results for high-spin states in 192Os populated in deep-inelastic reactions include the identification of a 2-ns, 12+ isomeric state at 2865 keV and a 295-ns, 20+ state at 4580 keV and their associated sequences. The structures are interpreted as manifestations of maximal rotation alignment within the neutron and proton shells at oblate deformation. Rotational band members based on the long-lived, isomer are also identified for the first time. Configuration-constrained, potential-energy-surface calculations predict that other prolate multi-quasiparticle high-K states should exist at low energy. [Copyright &y& Elsevier]

Abstract: The near-stable nucleus 184 75Re has been studied using the 180Hf(7Li, 3n)184Re reaction at 30 MeV. Prior to this work, a number of low-spin structures were known following transfer reaction experiments, but only three γ-ray transitions had been observed following the decay of a day, state. An extensive level scheme has been constructed from the present data, including states de-exciting through the isomer and the rotational band. Configurations are assigned with the aid of values and the comparison of energies with predictions of blocked BCS calculations. Finally, residual nucleon–nucleon interactions for orbitals in this region are collated. [Copyright &y& Elsevier]

Abstract: The properties of high spin states in 210Rn have been investigated using the 198Pt(17O, 5n) reaction at a bombarding energy of 96 MeV. Decay properties for states up to an excitation energy of and spin of (37−) have been deduced. The level scheme is compared with predictions of empirical shell model calculations. High lying states are interpreted in terms of multiparticle configurations which include single and double neutron core excitations. Configurations have been assigned for almost all of the observed levels. Agreement between experimental and calculated level energies is generally within 200 keV. [Copyright &y& Elsevier]

Abstract: A study of high spin states in the odd-neutron isotones 239Pu and 237U is reported. Striking differences were found in the high-spin properties of rotational bands built on the ground states in these two nuclei. These differences mirror those observed in the even–even Pu and U immediate neighbors and appear to be related to the strength of octupole correlations. [Copyright &y& Elsevier]
