Abstract: Nuclear resonance phenomenon is the creation of allowed states with high density for the distribution of nucleons in energy levels in the energy range of more than 2 mega electron volts. Such states are achieved in various reactions such as particle absorption or high-energy gamma. These changes lead to the rearrangement of symmetries of the system and the study of these processes is done using statistical methods based on the density of the levels.In this thesis, we became familiar with the concept of resonance energies, and especially the phenomenon of massive bipolar resonances. Then we classified the reactions of such energies based on the absorption of fast neutrons and the production of different gamma and for different nuclei using experimental information, we determined the resonance zone for different nuclei using experimental data. For even-even nuclei located in the mass range 50
