Description
High-spin states in doubly odd 170Re have been populated and investigated using 142Nd (32S, 1p3nγ)170Re reaction at 166 MeV bombarding energy, X-γ and γ-γ-t coincidence measurements have been carried out in the experiment. Based on the coincidence relationships, a rotational band in 170Re has been identified for the first time, extending the high-spin studies of A≅160 odd-odd nuclei to the currently lightest rhenium isotope. The band has been assigned to be built on the πh11/2 direct x υi13/2 configuration according to their rotational properties in quasiparticle alignment, signature splitting, level spacing systematics, as well as the existing knowledge in neighboring nuclei. Low-spin signature inversion has been suggested for the πh11/2 direct x υi13/2 band in 170Re
