Abstract

In this paper, energy levels of the high-spin states of nuclei has been studied. To retrieving energy levels, the levels were first labeled based on the SU(3) dynamical limit of the interaction boson model and then the results were calculated in both the three-level and two-level interaction boson models. It can be seen that the developed three-level interaction boson model has a great advantage over the two-level model, and the spectrum obtained for energy levels using this model is in good agreement with the experimental spectrum, which shows that this model in the description and recovering energy levels with high spin state is more successful. This model also works better in describing levels of high spin states than . Examining the results of energy level calculations, it was observed that the developed three-level interaction boson model in retrieving the levels of nucleus is better than , because nucleus shows a higher degree of deformation than due to its deformation parameter value.
