Nuclear Shape Transitions and Some Properties of Aligned‐Particle Configurations at Very High Spin in Some Rare‐Earth Nuclei

We will present results on an collective Δ I = 2 ground band level sequence in the spherical six‐valence‐particle nucleus 152 Dy and the variation of shapes for nuclei in the N = 88 to 92 transitional region. Finally, we will present results for some even‐even nuclei without any backbending behaviour, showed a clear backbending in the diagram of 2/ℏ 2 versus (ℏω) 2 .
