Done at current work the energy ground states GSB and negative parity band NPB for symmetric masses nucleus are calculated , used Bohr and Mottelson (B-M), Interacting Boson version one (IBM1) and Interacting Vector Boson (IVBM) Models to describe the characteristi of nucleus , where used different modalities like the relation between gamma energy divided by the spin (E-GOS) as a function of spin I and drawn. The relation between moment of inertia and the rotation frequency for emitted photons when the nucleus transitions from one to another state were drawn, only nuclei appears back bending that means changing its properties. the relation between the energy of different excitation states to the state of excitation that precedes it was used to find out the numerical value of this ratio and to determine the properties of each nucleus by knowing the value of this ratio. When studying the staggering phenomenon , it was found that the oscillation value did not reach zero in the each nuclei, which indicates the stability of its properties, The calculation shows different properties for each nuclei and there is agreement between the experimental and calculation specially at high spin
