Rotational bands and signature inversion in odd-odd 172Re
PHYSICAL REVIEW C 68, 054313 (2003),-0001,():
High-spin states in the odd-odd 172Re have been investigated via the 149Sm(27Al, 4nγ)172Re reaction through excitation functions, x-γ and γ-γ coincidence measurements. A level scheme consisting of three rotational bands 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 three bands have been assigned to be built on the πh11/2⊗νi13/2, πh9/2⊗νi13/2, and p1/2−[541]⊗ν1/2−[521] configurations according to their rotational properties in quasiparticle alignments, signature splitting, in-band B(M1)/B(E2) ratios, level spacing systematics, band crossing frequencies, as well as the existing knowledge in neighboring nuclei. Low-spin signature inversion has been confirmed in the first two bands due to the observation of signature crossing at high-spin states. The general features of inversion phenomenon in the semidecoupled bands are presented and discussed with reference to theoretical calculations of two quasiparticle plus rotor model including p-n interactions.
