“…configuration. In this portion "experimental" energies (points) fo r the ground-state decay sequence of I 6 8Hf9 6 (24), expressed in the intrinsic frame, are compared with cranking model (9) same rotational frequency, hm, in neighboring odd-N isotopes (26) and at significantly larger frequencies in the yrast band of the neighboring odd Z isotones (27,28), see Figure 5. The most alignable hll/ 2 quasiproton confi guration is occupied in the yrast configuration of the odd-Z isotone.…”

“…[41][42][43][44]. Recent level scheme information fo r N � 90 nuclei at I> 40 (20,21,26,28,45,46) allows the microscopic basis of angular momentum to be studied at even larger spins. Though these nuclei appear to be collective rotors at lower angular momenta, at the largest spins systematic deviations (47) from collective behavior are observed.…”

“…Though first nucleon alignments have been established and characterized in many deformed nuclei, the knowledge and understanding of subsequent alignments is limited, and discussions addressing the issue can be found for only a small number of nuclei, e.g., Refs. [15][16][17][18][19][20][21][22]. The characterization of nucleon alignments provides insight into the underlying configurations of rotational bands in addition to checking the validity of predictions of cranking calculations at high rotational frequencies.…”

“…4.10, the subtracted reference was based on the Harris parameterization [125] with the values 0 =32.1 −1 MeV 2 and 1 =34.0 −3 MeV 4 . This reference gives a constant alignment for the (−,+ 1 2 ) three-quasiparticle configuration (B p AB) in the oddproton neighboring nucleus 157 Ho [126], which is also displayed in Fig. 4.9 and Fig.…”

“…Therefore, configuration AE (a negative parity, odd-spin sequence) may be identified as configurations [126,171,172]. The subtracted reference, used to make these plots, was based on the Harris parameterization [125] with the values 0 =32 −1 MeV 2 and 1 =34 −3 MeV 4 .…”
