Abstract
A study of rotational properties of the ground superdeformed bands in 0, 2, 4, and 4 is presented. We use the cranked Hartree-Fock-Bogoliubov method with the parametrization of the Skyrme force in the particle-hole channel and a seniority interaction in the pairing channel. An approximate particle number projection is performed by means of the Lipkin-Nogami prescription. We analyze the proton and neutron quasiparticle routhians in connection with the present information on about thirty presently observed superdeformed bands in nuclei close neighbours of 2.
