Abstract
Total-Routhian-Surface calculations have been performed to investigate the shape evolutions of nuclei, Zr, Sr and Mo. Shape coexistences of spherical, prolate and oblate deformations have been found in these nuclei. Particularly for the nuclei, Sr and Zr, the energy differences between two shape-coexisting states are less than 220 keV. At high spins, the shell plays an important role for shape evolutions. It has been found that the alignment of the quasi-particles drives nuclei to be triaxial.
