In order to estimate octupole-induced E1 strength in very deformed nuclei we calculate their intrinsic dipole moments within the shell correction method. We use the formula for the macroscopic part of the dipole moment derived by Dorso, Myers, and Swiatecki, however, without approximation limiting its validity to small deformations. We obtain rather large dipole moments in superdeformed Hg and Pb nuclei, in agreement with recent Hartree-Fock calculations. This points to the possibility that in these nuclei interband E1 transitions may be detectable in spite of enormous competition of superdeformed intraband E2 transitions. We give also estimates for dipole moments of even more deformed systems.
