    "abstract": "The possible existence of stable axial octupole and tetrahedral deformations\nis investigated in $^{80}$Zr and $^{98}$Zr. HFBCS calculations with parity\nprojection have been performed for various parametrizations of the Skyrme\nenergy functional. The correlation and excitation energies of negative parity\nstates associated with shape fluctuations have been obtained using the\ngenerator coordinate method (GCM). The results indicate that in these nuclei\nboth the axial octupole and tetrahedral deformations are of dynamic character\nand possess similar characteristics. Various Skyrme forces give consistent\nresults as a function of these two octupole degrees of freedom both at the\nmean-field level as well as for configuration mixing calculations.",
