Study of Barrier Coulomb, Concept of Trajectory, the Impact Factor, and Grazing Angle in Heavy Ion Collision

We have a detailed analytical study of the Coulomb barrier, the concept of collision factor, the concept of the trajectory, and the concept of grazing angle in a collision between heavy nuclei, and that for many of the symmetrical systems A1 equal A2 and asymmetric systems A1 doesn't equal A2 .The results obtained and presented for the first time in this way, help to differentiate between the electric interaction and the nuclear reaction, and then determine the energy ejaculation that should be used in order to show the interaction to be studied. On the one hand, on the other hand this helps to choice the detector (or detectors) that must be used in experimental work, and then where to put this detector (or these detectors).
