✦ Synopsis

The quark contining two-step potential used earlier for mesons is now applied to nucleons. By using the Coulomb part of this potential for the quark-quark pair we investigate the predictions of the quark-diquark (QDQ) model for the nucleons. It is found that this kind of composite model, consistent for both the proton and the neutron, not only accounts for the recent data on the nucleon form factors but also provides a deeper understanding of the already available results in such a model. Further, it is noticed that the present QDQ model, accounting satisfactorily for various properties of the nucleon, offers an alternative way to investigate the ground state of deuteron and the nature of nucleon-nucleon force in terms of the pre-Yukawa picture of chemical-type forces. The results obtained in this alternative approach are found to be in agreement with those obtained by other conventional calculations.
