“…In summary the present work shows that: i) the nhl 1/2 x vij 3[2 structure proposed in [1] for the yrast bands in both nuclei (16~ and 162Tm) is confirmed by the observed crossing frequencies which correspond to the second neutron backbending (BC), ii) the similarity of the high spin level structure between the 162Tm and 164Tm nuclei emphasized in [8] is broken for J 6~ While the il 3/2 neutron component is the only one involved in the observed bands in 162' 164Tm, an additional neutron component (h9/2) is competing in 16~…”

“…This concept has been successfully employed in the A ∼ 160-170 region, see Refs. [15,16,23], for example. In the previous high-spin study of 168 Ta [16], the two observed bands were interpreted as structures resulting from the coupling of proton states in 167 Ta and neutron states in 167 Hf.…”

High-spin states in the odd-odd nucleus 168 Ta have been populated in the 120 Sn( 51 V,3n) reaction. Two multi-quasiparticle structures have been extended significantly from spin ∼ 20h to above 40h. As a result, the first rotational alignment has been fully delineated and a second band crossing has been observed for the first time in this nucleus. Configurations for these strongly-coupled rotational bands are proposed based on signature splitting, B(M 1)/B(E2) ratio information, and observed rotation-alignment behavior. Properties of the observed bands in 168 Ta are compared to related structures in the neighboring odd-Z, odd-N , and odd-odd nuclei and are discussed within the framework of the cranked shell model.

“…26) This method determines band head spins and K quantum numbers by considering the projection of angular momentum on the rotational axis, and was successfully applied to odd-odd 162;164 Tm. 26) In the present work, we used 5.0 h " for the neutron alignment of the i 13=2 shell ( 165 Yb) as shown in Fig. 11.…”

“…22) We used 165 Yb data instead of 167 Yb due to the lack of its alignment data. The Harris parameters of a reference frame for 168 Lu were taken the same as those of 166 Yb: 23) 22) The alignments for both signatures ( ¼ 0, 1) are shown to be the sum of two alignments of 7/2 þ [404] (with both ¼ þ1=2, À1=2 of 167 Lu) and 5/2 þ [642] (only with ¼ þ1=2 of 165 Yb), which confirms the additivity that i np exp ' i n exp þ i p exp .

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.
