Total-Routhian-surface calculations have been performed to investigate the shape evolutions of A similar to 80 nuclei: Zr80-84, Sr76-80, and Mo-84,Mo-86. Shape coexistences of spherical, prolate, and oblate deformations have been found in these nuclei. Particularly for the nuclei Sr-80 and Zr-82, the energy differences between two shape-coexisting states are less than 220 keV. At high spins, the g(9/2) shell plays an important role in shape evolutions. It has been found that the alignment of the g(9/2) quasiparticles drives nuclei to be triaxial.
