Observation of new h9/2 and h11/2 bands in 187T1
Abstract
The unfavoured signature of the rotation-aligned band associated with the prolate h9/2 structure in 187T1 has been identified. The deformation-aligned 11/2−[505] band is also confirmed and extended. While the alignment properties of the 11/2−[505] band seem to indicate that it has a similar magnitude of deformation as the prolate 186Hg core, the signature splitting at low spin, taken together with new self-consistent calculations, suggest that it may actually be triaxial with γ ≈ −180 near the bandhead.
