He believes the nuclear structure is similar to that of the solar system. Including protons, neutrons and electrons, all particles are made up of other smaller particles. The smallest particle is photon. At this time, the experimental studies were carried out. We let the neutrons pass through the high-voltage electrostatic field to observe what will happen. As the result, we discover the position of image changes. Thus, we can infer that the neutrons deflect in the electric field. In the end, two examples are given about how to re-recognize the common electromagnetic phenomena. http://pubs.sciepub.com/ijp/7/1/5/ijp-7-1-5.pdf nuclear structure neutron electron scale line electromagnetic theory
