# Non-axial octupole deformations of N=Z nuclei in A{approx}60-80 mass region

## Abstract

By performing a fully three dimensional Hartree-Fock calculation with use of the Skyrm forces, we demonstrate possibility of exotic deformations violating both the reflection and the axial symmetries of N=Z nuclei in A{approx}60-80 mass region. The Y{sub 32} tetrahedral shape predicted in excited {sup 80}Zr arises from a shell gap at N,Z=40 which is enhanced for the tetrahedron deformation. Softness toward the Y{sub 33} triangular deformation of the oblate state in {sup 58}Se is also predicted.
