Abstract：
The bandcrossing in the K=1/2 bands of odd-A nuclei was discussed in the particle-rotor model.The decoupling term in the rotational energy expression has a remarkable effect on the backbending frequency,which,in the band built on the [541]↓orbital,leads to a bandcrossing delay comparable with the observa tions.
