“…Several members of the y-vibrational band have been observed earlier in the radioactive decay of 166Lu [3]. The 5+ member of this band is populated rather strongly in the present study and angular distribution and the conversion electron data confirm the 5' assignment.…”

“…The level at 1865 keV, which lies at the bottom of the even-spin negative parity band, has been observed in the radioactive decay of 166 J h [3] and assigned a spin and parity of 6-. The regularity and the stretched E2 character of the cascade transitions populating this level justify the classification of this cascade as a band.…”

“…The yrast sequence of levels in 166.yb was earlier known up to spin 20' . Many low-lying levels up to an excitation energy of 2.43MeV are known from the radioactive decay studies [3] of 166Lu. The level scheme of 166Yb, as deduced from the present work, is presented in Fig.…”

“…The intraband transitions among the 5; 7-, 9-and the 11-states at 1790, 1959, 2209 and 2417keV are too weak to be detected in the coincidence work. The 5 -and 7-states are known from the work of de Boer et al [3]. The stretched El character of the transition from the 9-state to the 8' member of the g.s.b.…”

High-spin states in '66Yb have been studied via the '"Sm("0, 4n)'66Yb reaction with 80MeV I6O ions from the NBI tandem accelerator. y y coincidence data were accumulated with an array of four Ge(Li) and four NaI(TI) detectors to favour high multiplicity events. Totally about 3 X lo8 events were accumulated in the coincidence experiment. Measurements of the angular distribution of the yradiation and the conversion coefficients were furthermore performed. Four weakly populated side bands are observed besides the yrast cascade which is followed up to its 24' member. The ground state band has thus been identified to its 18' state, while the crossing Stockholm band becomes the yrast band from its 16+ member. The S-band is established from its 12+ state. The observed level energies and transition rates are well reproduced in-calculations within the particle rotor model.

“…The 168Lu nucleus has one isomer with Tx/2 =6.7 min [2]. Two isomers were found in 166Lu with half-lives of 2.1 min and 1.4 min in addition to the ground state decay with 7"1/2=2.6 min [3]. Hunter et al I-4] have suggested an isomeric state in 164Lu with half-life of approximately 2rain and our measurements in 162Lu have shown the presence of two fl+-decaying levels with T1/2=93 s and 81 s [5].…”
