Abstract: The excitation energies of ground and gamma bands belonging to F0 spin multiplets of Xe-Gd nuclei are found to be constant. The pair conjugates nuclei with the same F-spin and ±F0 values also have identical NpNn values. The smooth dependence of moment of inertia and function of valence proton and neutron number [f(NpNn)] give the existence of low-spin identical bands in this region. A correlation ansatz to identify such nuclei based on the concepts of NpNn and F-spin is also discussed.

Keywords: identical spectra; Xe-Gd nuclei; NpNn scheme; F-spin multiplets; low-spin identical bands; xenon; gadolinium.
