  A systematic investigation of the yrast superdeformed (SD) rotational bands
in even-even nuclei of the $A\sim 190$ mass region has been performed within
the framework of the cranked relativistic Hartree-Bogoliubov theory. The
particle-hole channel of this theory is treated fully relativistically, while a
finite range two-body force of Gogny type is used in the particle-particle
(pairing) channel. Using the well established parameter sets NL1 for the
Lagrangian and D1S for the Gogny force, very good description of experimental
data is obtained with no adjustable parameters.
