The moments of inertia of deformed atomic nuclei at low spins are a factor of 2 or 3 smaller than the rigid-body value. The reduction is attributed to the strong pair correlations, because nuclei in… (More)

In a schematic model with equidistant fourfold degenerate single-nucleon levels, an isovector pairing force acting only on pairs with time-reversed orbits and spins, and a symmetry force, the RPA… (More)
