A quantum mechanical description of composed particle interactions and the swelling of nucleons in nuclei

For describing quantum mechanical interaction of composed particles the authors have proposed a new approach founded on a minimal generalization of conception of the potential type interaction. The elastic electron scattering from the deuteron is considered in an illustrative example. It is shown for this case that a self-concerted interpretation of their results within the framework of the conventional potential theory is accompanied by the effective swelling of nucleons in the deuteron, with the increase of the isoscalar nucleon charge radius by ε ≤ 2%
