We study the problem of giant nuclear oscillations by performing self-
consistent calculations in semiclassical approximation utilizing a mul
tipole-multipole interaction of the Bohr-Mottelson type for quadrupole
and octupole deformations. In all cases considered we find regular mo
tion of the collective coordinate, the multipole moment of deformation
. This is in contradiction to the predictions of the wall formula and
suggests that this type of one-body dissipation might not be realized
in real nuclear systems. In addition, we find chaotic single particle
motion in coexistence with the regular collective dynamics.
