High-spin states in odd-odd 174Re

High-spin states in the odd-odd 174Re have been investigated via the 152Sm(27Al, 5nγ)174Re reaction with the help of excitation function, x-γ, and γ-γ coincidence measurements. Five rotational bands have been observed and their configurations were assigned based on alignments, band crossing frequencies, electromagnetic properties, and the estimated bandhead excitation energies. Low-spin signature inversion has been identified in the two-quasiparticle bands built on πh 11/2νi 13/2, πh 9/2νi 13/2, and π1/2 -[541]ν5/2 -[512] configurations. E2 interband transitions were analyzed with band-mixing calculations giving information on shapes and shape driving effects for the bands of interest. © 2012 American Physical Society.
