Calculations of pairing energies in multi-quasiparticle states using the Lipkin-Nogami prescription predict a discrete reduction in pairing with a geometric dependence on seniority. An abrupt transition from superfluid to normal motion is therefore not expected, even with a large number of orbits blocked. Recent experimental results on rotational bands associated with multi-quasiparticle intrinsic states allow comparisons to be made for a subset of orbitals as a function of seniority. Approximate agreement is obtained between the observed moments-of-inertia and calculated values supporting the view that for the highest seniority states identified so far, the pairing persists at nearly half of the full value.
