Calculations are reported of the inertia and stiffness associated with octupole vibrations of nuclei in the region of 136 neutrons. The calculations are based on Nilsson's strong coupling model and include approximately the effects of residual pairing interactions. The results indicate a clear quantitative discrepancy with the observed vibrational energies. However, the calculations exhibit two enlightening qualitative features: (a) nuclei in this region are hardly stable against small octupole deformations aad (b) the frequency of octupcle vibrations is quite sensitive to the magnitude of the quadrupole deformation. The part of the nuclear dipcle moment arising from the difference between the wave functions of the neutrons and those of protons is computed and shown to be comparable but somewhat smaller than the part due to electric polarization. The electric polarization, however, is uncertain even as to sign. (auth)
