Abstract：
The power index formula has been used to obtain the band head spin (I₀) of all the superdeformed (SD) bands in Hg isotopes. A least squares fitting approach is used. The root mean square deviations between the determined and the observed transition energies are calculated by extracting the model parameters using the power index formula. Whenever definite spins are available, the determined and the observed transition energies are in accordance with each other. The computed values of dynamic moment of inertia J⁽²⁾ obtained by using the power index formula and its deviation with the rotational frequency is also studied. Excellent agreement is shown between the calculated and the experimental results for J⁽²⁾ versus the rotational frequency. Hence, the power index formula works very well for all the SD bands in Hg isotopes expect for ¹⁹⁵Hg(2, 3, 4).
