“…Where ϕ 0 , ∆ 0 and ν are the free parameters of the model, which are adjusted to give a least-square fit to the experimental data. This approach is supported by Ma and Rasmussen suggestion that there is an exponential dependence of the moment of inertia on the parameter ν for a wide range ν values [18].…”

Recent studies of the backbending phenomenon in medium light weight nuclei near A ∼ 60 expanded greatly our interest about how the single particle orbits are nonlinearly affected by the collective motion. As a consequence we have applied a modified version of the exponential model with the inclusion of paring correlation to describe the energy spectra of the ground state bands and/or the backbending phenomenon in mass region at A ∼ 60. A firm conclusion is obtained concerning the successful validity of the proposed modified model in describing the backbending phenomenon in this region. Comparison with different theoretical descriptions is discussed.

“…Previous work [17] proved that the exponential dependence of the moment of inertia on the parameter ν is valid for a wide range of ν values. Also, Zhou and Zheng [16] used I c = 85h in their calculations for the A = 190 region since backbending phenomena some times do not appear before I ∼ 50h and the pairing correlation in that region is still strong at high rotational frequency hω = 0.5 MeV.…”

In the present work the nuclear structure properties and the backbending phenomena of eveneven isotopes at A ≈ 70 mass region are analyzed using two simultaneous theoretical models based on a simple modified version of the collective model predictions besides an improved version of exponential model with the inclusion of pairing correlation. In general, both models successfully describe the backbending phenomena in that region. From the comparison between the predictions of the two proposed models a firm conclusion is obtained concerning the superiority of the simple improved version of the exponential model in describing the forward and downbending region of the φ-ω 2 plots.
