Lifetimes of excited states in the neutron-deficient odd-odd nucleus 166 Re have been measured for the first time using the recoil distance Doppler-shift method. The measured lifetime for the (8 − ) state; τ = 480 (80) ps, enabled an assessment of the multipolarities of the γ rays depopulating this state. Information on electromagnetic transition strengths were deduced for the γ -ray transitions from the (9 − ), (10 − ), and (11 − ) states, and in the case of the (10 − ) and (11 − ) states limits on the B(M1) and B(E2) strengths were estimated. The results are compared with total Routhian surface predictions and semiclassical calculations. Tilted-axis cranking calculations based on a relativistic mean-field approach (TAC-RMF) have also been performed in order to test the possibility of magnetic rotation in the 166 Re nucleus. While the TAC-RMF calculations predict a quadrupole-deformed nuclear shape with similar β 2 deformation as obtained by using the TRS model, it was found that the experimental electromagnetic transition rates are in better agreement with a collective-rotational description.

“…After the discovery of magnetic bands in 199,200 Pb [8], the neighboring Pb isotopes attracted many studies [16,17]. Nevertheless, the level schemes of most of the nuclei are incomplete with bands not connected to the lower lying levels.…”

High-spin states in 194 Pb have been populated in the 168 Er( 30 Si,4n) reaction at 142 MeV. The emitted γ rays were detected by the EUROBALL III multidetector array. The level scheme was considerably extended and many previously observed γ -ray transitions were reordered. Four new magnetic rotational bands were observed. The energies and spins of the bandheads of all previously observed magnetic rotational bands were corrected based on the observation of new transitions. From nine observed bands, only one could not be connected to the lower lying states. Based on comparison systematics with neighboring Pb isotopes and tilted-axis cranking model calculations previously reported, configuration assignments to the observed bands have been made.

“…Numerous magnetic rotational bands have since been observed not only in the mass region A ∼ 190, but also at A ∼ 140, ∼ 110, and ∼ 80. More than 130 magnetic dipole bands have now been identified in these four mass regions [41]. The presence of magnetic rotational bands in the f p shell, however, is extremely scarce.…”
