Journal ArticleDOI
Slow and fast high-spin sequences in 158Er.
P.O. Tjøm,R. M. Diamond,J. C. Bacelar,E. M. Beck,M. A. Deleplanque,J. E. Draper,F. S. Stephens +6 more
TL;DR: Four slower y rays suggest a transition to a different shape and structure, most likely to an oblate 46+ state with all valence particles maximally aligned, a band termination in 158Er.
Journal ArticleDOI
Superdeformed band in 135Nd.
Journal ArticleDOI
Superdeformed bands in Nd nuclei
E. M. Beck,R. J. McDonald,A. O. Macchiavelli,J. C. Bacelar,M. A. Deleplanque,R.M. Diamond,J. E. Draper,F.S. Stephens +7 more
TL;DR: In this paper, superdeformed bands were found in 134, 136 Nd. Their dynamic moments of inertia were about as large as those of the known superdeform bands in 135 Nd and 132 Ce, corresponding to β ≈ 0.5.
Journal ArticleDOI
High-spin state spectroscopy in 165, 166Yb
E. M. Beck,J. C. Bacelar,M. A. Deleplanque,R.M. Diamond,F.S. Stephens,J. E. Draper,B. Herskind,Anders Holm,P.O. Tjøm +8 more
TL;DR: In this paper, triple γ-ray coincidence spectra of 165Yb and 166Yb were analyzed for the first time and the observed bands in both nuclei were interpreted in terms of the cranked-shell model.
Journal ArticleDOI
Lifetime measurements of high-spin states in 166Yb.
J. C. Bacelar,Anne I. S. Holm,R.M. Diamond,E. M. Beck,M. A. Deleplanque,J. E. Draper,B. Herskind,F.S. Stephens +7 more
TL;DR: The Doppler-shift attenuation method was used to measure lifetimes of yrast states in /sup 166/Yb, indicating a loss of collectivity which likely reflects a change of the nucleus towards triaxial shape.
