The Department of pathological analyzes at the Faculty of science at the University of Basrah organized a scientific lecture on ( the order of appearance of +J = 0 levels and the packet structure of some paired nuclei of selected( Zr )and (Ge) isotopes) .
The lecture, in which the lecturer Marwa Salahuddin Mahdi was present, aimed at studying the energy levels using the 1-IBM model and studying the effect of irritation using the model of interacting bosons with mixing IBM-CM formations at the energy levels of zirconium isotopes Zr86-106 and germanium isotopes Ge66-78 and comparing them with practical values.
The lecture included the study of the relationship between the energy levels and the number of neutrons outside the closed shell through the forms of this relationship as well as calculating the probability of the reduced electric quadrupole transition of the isotopes under study .
