%X In this article nucleons are discussed based on constituent quark model. This model aims at studying the forces among three particles and the corresponding standard two-body potential contribution. The quark potential contains a hypercentral interaction. The confining potential is composed of four components,color charge, the oscillatory potential, the interaction quark and neutral gluon, and the dipole ¨C dipole electromagnetic interaction. Dirac equation can be solved carefully and analytically by means of these potentials. In addition to the above potentials, there is a hyperfine potential which is related to isospin ¨C isospin and spin ¨Cisopin interactions. These potentials were considered as perturbation potentials and their energy shift was calculated.
