Abstract

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 plus BCS calculation with no restrictions on the nuclear shape. The calculation predicts that the oblate ground state in $^{68}$ Se is extremely soft for the $Y_{33}$ triangular deformation, and that in $^{80}$ Zr the low-lying local minimum state coexisting with the prolate ground state has the $Y_{32}$ tetrahedral deformation.
