Excited states in the odd-odd, highly neutron-deficient nucleus 166 Re have been investigated via the 92 Mo( 78 Kr, 3p1n) 166 Re reaction. Prompt γ rays were detected by the JUROGAM II γ -ray spectrometer, and the recoiling fusion-evaporation products were separated by the recoil ion transport unit (RITU) gas-filled recoil separator and implanted into the Gamma Recoil Electron Alpha Tagging spectrometer located at the RITU focal plane. The tagging and coincidence techniques were applied to identify the γ -ray transitions in 166 Re, revealing two collective, strongly coupled rotational structures, for the first time. The more strongly populated band structure is assigned to the πh 11/2 [514]9/2 − ⊗ νi 13/2 [660]1/2 + Nilsson configuration, while the weaker structure is assigned to be built on a two-quasiparticle state of mixed πh 11/2 [514]9/2 − ⊗ ν[h 9/2 f 7/2 ]3/2 − character. The configuration assignments are based on the electromagnetic characteristics and rotational properties, in comparison with predictions from total Routhian surface and particle-rotor model calculations.

“…8) Signature inversion, also known as anomalous signature splitting, has been also observed in the yrast h 11=2 i 13=2 band in lighter odd-odd Lu isotopes of A ¼ 160, 162, 164 and 166. 9) For those interesting phenomena in odd-odd nuclei, the n-p interaction may well play an important role in the onset of unusual nuclear structures pertaining to odd-odd nuclei. However, theoretical calculations taking into account the np interaction have not been conclusively exploited to resolve those phenomena.…”

We observed four rotational bands in 168 Lu using the 159 Tb( 13 C,4n) 168 Lu reaction at 58.5 MeV and 62 MeV and populated high spin states up to 27 h " . On the basis of the X-gating procedure and excitation function measurements done at beam energies of 50, 55, 58.5, 60, 62 and 64 MeV, we could identify the -ray transitions belonging to 168 Lu. The configurations of two strongly populated rotational bands (bands A and B) were based on our previous study and were examined by using the additivity relation for alignments. The configurations of two newly found rotational bands (bands C and D) were also assigned by the additivity relation. These identified configurations were confirmed by the Drissi's recipe and energy systematics of neighboring odd-odd nuclei. The configuration of bands A was assigned as K ¼ 6 þ ½7=2 þ ½404 þ 5=2 þ ½642. The configurations of the previous reported band B and two new bands C and D are likely to be 3 À ½1=2 À ½541 þ 5=2 þ ½642, 7 À ½9=2 À ½514þ 5=2 þ ½642 and 5 þ ½5=2 þ ½402 þ 5=2 þ ½642, respectively. We observed band crossing for three bands A, C and D, but not for band B. The extracted band crossing frequencies were consistent with the neutron BC crossing observed in neighboring odd-odd nuclei as well as odd-N and even-Z nuclei in this mass region. This was attributed to the occupied 5=2 þ ½642 Nilsson configuration arising from the neutron i 13=2 orbital. Energy systematics of bands built on g 7=2 i 13=2 and h 11=2 i 13=2 in neighboring odd-odd nuclei were also studied in comparison with bands A and C in 168 Lu.
