Blocking effects at super-deformed shape

The strongly reduced blocking effect in the supper-deformed HgPb region is investigated by means of the cranked Strutinsky pairing and deformations selfconsistent Lipkin-Nogami approach including both monopole and quadrupole pairing interaction. The simultaneous reduction of monopole and quadrupole pair correlations due to blocking has opposite effect on the dynamical moments of inertia. This provides an additional cancellation mechanism that levels out the difference between odd and even nuclei.
