“…This work led us to introduce a simple three-parameter formula based on the exponential model with paring attenuation for the description of the backbending phenomena, by letting ν to be a free parameter and using a suitable I c values to represent both, the variation of the moment of inertia and the pairing correlation. This extension has been previously applied to predict the energy levels of doubly even actinide nuclei leading to a significant improvement [18]. The model not only describes the backbending of the moment of inertia in the well-deformed nuclei but its validity also extends to include the slightly deformed nuclei.…”

A study of the superdeformed (SD) bands of [189][190][191][192][193][194][195] Hg is carried out within the standard and the modified exponential models. The SD transition energy bands and moments of inertia and the models parameters for these bands are calculated within these two models. Comparison between these two models has been undertaken to implement their validity for these bands. The two models exhibit different behavior at high rotational angular frequency. Both models reproduce well the kinematic moments of inertia in this mass region. At high angular frequency the modified exponential model successfully reproduces the uprising and the down-turn of the dynamic moments of inertia of the studied SD bands. moment of inertia ( (2)J ) is initially rapidly decreasing. Figs 1-4 show that both models fit well the experimental data for the kinematic moments of inertia.

Abstract:In the paper calculation of the moments of inertia for nuclei from the region 87 ≤ Z ≤ 100 and 130 ≤ N ≤ 156 was made in dependence on the angular momentum of their rotational states. The experimental values of the moments of inertia were calculated for rotational energy of the classic rotor in its quantum form, with the use of a simple formula. The moment of inertia term appearing in the formula was treated as a variable. The calculations were carried out on the basis of experimental data for the energies of the rotational levels for 51 bands built on ground states for even-even nuclei and for nuclei with odd mass number A. In addition, 30 rotational bands built on excited states were also analysed in the investigated region in case of eveneven nuclei. For many bands and nuclei the considered dependence of the moment of inertia on angular momentum has been found in the analytical form by fitting polynomials to the experimental data. It turned out that obtained results for the moments of inertia made it possible to describe the energies of rotational levels with a relative deviation not greater or only slightly greater than 1%. In general, in the case of 12 bands of ground level the maximum relative deviation of obtained level energies is smaller than 1‰. PACS
