Effect of alignments on the shape of /sup 158/Yb
Journal Article
·
· Phys. Rev. Lett.; (United States)
Levels in /sup 158/Yb have been established up to 38h-bar in the yrast band and about 30h-bar in two sidebands. Below spin 20, the similarity to the isotone /sup 156/Er is striking, but up to spin 34 /sup 158/Yb remains rather collective while /sup 156/Er becomes triaxial and evolves toward an oblate shape. This appears to result from small shifts in particle-alignment (backbend) frequencies; a proton alignment occurs before neutron ones in /sup 158/Yb, whereas the reverse is true in /sup 156/Er.
