摘要The influence of the gap at Z=70 on the alignment in 161−168Yb is studied using the particle number conserving method. If there is a gap at the Fermi surface, the occupation probability of the [523]7/2 proton orbital does not change as much as when there is no gap. The formation of the plateau of moment of inertia is sensitive to the relative position of the orbital π[404]7/2, π[411]1/2 and π[523]7/2. A third backbending caused by π[541]1/2 is predicted.
