A more detailed systematic study of identical bands in the A = 150 and 190 mass regions wasperformed to gain further insight into the occurrence of identical bands with the projected shell model andthe energy factor method. The results show that the number of identical bands in super deformed nuclei ismuch more than that in the normal-deformed nucleus at low spin and this difference may be result from A more detailed article study of identical bands in the A = 150 and 190 mass regions was formed into gain further insight into the occurrence of the same bands with the projected shell model and the energy factor method.
