Tetrahedral and Triangular Deformations of $Z=N$ Nuclei in Mass Region $A\sim 60-80$

S. Takami, K. Yabana, M. Matsuo

We study static non-axial octupole deformations in proton-rich $Z=N$ nuclei, ${}^{64}$Ge, ${}^{68}$Se, ${}^{72}$Kr, ${}^{76}$Sr, ${}^{80}$Zr and ${}^{84}$Mo, by using the Skyrme Hartree-Fock p…
