  An angular momentum dependence of the parity splitting in the alternating
parity bands of nuclei with strong octupole correlations is considered basing
on the model of the octupole motion in a one-dimensional potential well
conserving axial symmetry. A sign reversal of the parity splitting at higher
values of the angular momentum is interpreted as a result of the Coriolis
coupling to K=1 octupole mode. New experimental data on the spectra of the
alternating parity octupole bands are used.
