Abstract

By analyzing carefully the inbeam γ spectroscopy data of odd-odd ¹⁷⁴Re, we have extracted the branching ratios of the interband and intraband E2 γ transitions from the two rotational bands of different configurations in ¹⁷⁴Re.The ratios of the reduced transition probabilities B(E2) have been deduced and analyzed using a band mixing theory. Information on the band interaction and deformation have been obtained. Apparent differences of transition quadrupole moments are found in the two configurations. A likely reason for the differences in the transition quadrupole moments is the shape driving effects of 1/2^-541 quasiproton or 1/2^-521 quasineutron, which has been proposed in the odd-A neighbors of ¹⁷⁴Re.
