Microscopic analysis of the quantum (shell) effects related to the presence of the hexadecapole ({ital Y}{sub 4{mu}}; {mu}=0,2,4) components in the nuclear mean field is performed for the superdeformed nuclei in the mass {ital A} {similar_to} 150 region using the deformed Woods-Saxon potential. No shell effects favoring the {ital C}{sub 4}-symmetry are found. The calculations indicate, however, the existence of the {alpha}{sub 44}-deformation driving orbitals whose occupation might induce an {alpha}{sub 44}-polarization effect. For {sup 149}Gd and {sup 153}Dy nuclei, in which the existence of the {ital C}{sub 4}-symmetry effects is suspected, properties of several excited particle-hole configuration are analyzed.
