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