Abstract
Several signature partner pairs in super-deformed rotational bands in the A = 190 mass region have exhibited ΔI = 1 staggering effects in its transition energies. A total of twenty signature partner pairs of super-deformed (SD) rotational bands in the A = 190 mass region were investigated in this study. The intrinsic structure and the band head moment of inertia J 0 of these signature partner pairs were found to be identical. The band head spin I 0 and the band head moment of inertia J 0 of these pairs were assigned by using the VMI (variable moment of inertia) equation. The ΔI = 1 staggering was also examined through the staggering index S(I) formula, where interlinking transition energies between signature partner pairs were experimentally known. A large amplitude staggering was observed in these signature partner pairs. The paper indicates the possibility of a high signature splitting property and will be useful for further studies.
