Interacting boson model description of octupole states in nuclei
Journal Article

· Ann. Phys. (N.Y.); (United States)
The IBM-1+f-boson model is described and systematically applied to the nuclei /sup 154/Sm, /sup 156/Gd, /sup 158/Gd, /sup 158/Dy, /sup 162/Dy, /sup 168/Er, /sup 172/Yb, /sup 178/Hf, and /sup 182/W. Reasonable agreement with available energies and B(E3) transition rates is obtained in all cases except /sup 162/Dy, which has the anomalous octupole band order K/sup ..pi../ = 2/sup -/, 0/sup -/, 1/sup -/. This energy ordering of K/sup -/ bands cannot be obtained within the present model. The parameter trends show considerable variation, indicating that the underlying fermionic subshell structure is very important in octupole states. copyright 1988 Academic Press, Inc.
