  The cranked Hartree-Fock-Bogoliubov method presented in previous studies of
superdeformed bands in Hg and Pb isotopes is applied to the study of
superdeformed bands in Gd150, Dy152, Dy151 and Tb151. The same
density-dependent zero-range pairing interaction used in the A=190 mass region
leads to a similarly good agreement with the experimental data. In particular,
our results confirm the importance of a correct treatment of pairing
correlations in Gd150 to reproduce its experimental dynamical moment of
inertia. The quasi-particle spectra obtained for all the nuclei studied here
are compatible with the experimental results obtained for excited bands in this
mass region. The quality of our results opens the possibility of studying
microscopically very subtle phenomena like the properties of identical bands.
