Crossings between unpaired rotational bands at I ≈ 30 in the N ≈ 90 region

Bengtsson, Tord and Ragnarsson, Ingemar LU (1985) In Physics Letters B 163(1-4). p.31-36
Abstract

It is shown that the band crossings observed at frequencies ≈h{stroke};hω ≈ 0.5 MeV can be qualitatively explained from Nilsson-Strutinsky calculations with no pairing correlations. The crossing bands are characterized by a different number of protons in h 11 2 orbitals leading to different deformationtrajectories in the (∋, γ)-plane. Above the band crossings, the calculated transition energies come very close to the observed ones in all cases studied.
