Abstract
The properties of superdeformed (SD) bands of isodiaphere nuclei (,,) have been studied in the scope of four and five parameters’ formulas of the Bohr-Mottelson collective model. The unknown parameters are obtained by fitting the experimental measurements of the gamma-ray transition energies using MATLAB software. The rotational frequency , the kinematic , and dynamic  moments of inertia are determined by using the best fitted parameters. The obtained 𝛾-ray transition energies 𝐸𝛾 are in good agreement with the experimental measurements. Also, the theoretical results of the kinematic , and dynamic  moments of inertia using both formulas agree well with the experimental data. The staggering  phenomenon is represented by using various order derivatives of g-ray transition energies  with respect to spin angular momentum I. We conclude that the five parameters formula of Bohr-Mottelson collective model successes in interpreting the appeared pairing correlations in the experimental measurements for the studied nuclei.
