Description
We present an analysis of all the known superdeformed (SD) bands in 193Pb using the modified variable moment of inertia (VMI) model to obtain the values of unknown band-head spin (I0) along with the level spin. The band-head spin so estimated is not known experimentally in band-7, 8 and 9. A total of 9 experimentally known SD bands of 193Pb have been analyzed. Quantitatively good results of the γ energies and the spins for Pb band are successfully obtained. We also examine the ratio of transition energies over spin Eγ/2I (RTEOS) to confirm the correct spin of the band-head and level spins by theVMI equation. The calculated and observed transition energies agree quite well. In the present paper, we have reported the band-head spin for the 193Pb (b7-b9) superdeformed band. Out of the available 9 SD bands, the band-head spin is predicted for 3 SD bands, where the band-head spins are not known experimentally. As an important outcome of our study, we propose the spin assignments and level energies of the 193Pb (b7-b9). We resolve the tentative nature of the assignments and present the unique level schemes. These results may be useful for the future studies.
