Abstract：
The E-Gamma Over Spin (E-GOS) analysis method is applied to study the shape evolution of yrast-bands in A～150 nuclei.The results show that the vibration and the rotation coexist in this region. There is a critical point and the nuclear structure changes notably at this critical point. It is found that these nuclei in A～150 region are in the transition from U(5) to SU(3) dynamical symmetry.
