Query: Nuclear Shell Structure and Chaotic Dynamics in Hexadecapole Deformation   The effect of an axially symmetric hexadecapole term is investigated in a
strongly deformed quadrupole potential. While the system is nonintegrable and
shows significant chaotic behaviour classically, the quantum mechanical
treatment not only produces a general smoothing effect with regard to chaos but
even yields a pronounced shell structure at certain hexadecapole strength
parameter values for oblate and prolate deformation.
