Abstract: | The systematics of kinematic moment of inertia J~((1))and dynamic moment of inertia J~((2))of superdeformed(SD) bands in A~130, 150, 190 mass regions have been studied. We have obtained the values of J~((1))and J~((2))for all the SD bands observed in the A~130, 150, 190 mass regions by using the experimental intraband E2 transition energies. The result of this work includes the variation of J~((1))with the product of valence proton and neutron numbers(N_pN_n). The phenomenon of band mixing has been observed in the A~130, 150 mass regions and band crossing has been observed in the A~190 mass region. The systematics also includes the variation of J~((2))with the product of valence proton and neutron numbers(N_pN_n). Evidence of staggering behaviour has been observed in all three A~130, 150 and 190 mass regions. We present for the first time the variation of J~((1))and J~((2))of SD bands in the A~130, 150, 190 mass regions with N_pN_n. |
