Statistical analysis of pairs of rotational bands in “odd and even” nuclei at normal deformation

A statistical analysis has been done for the variation of the moment of inertia in pairs of rotational bands between odd-A and adjacent A - 1 even-even nuclei at normal deformation. A smooth distribution centered at small differences or no difference is obtained but apart from this, no special surplus of so-called identical bands is found. Furthermore, it is found that upsloping orbitals are predominantly involved when forming bands with similar moments of inertia
