Are all models of the NN interaction independent of each other?

Models of the NN interaction are most often considered as independent of each other, and it is generally believed that experiments could allow one to discriminate them. It has, however, been shown that there may be some relationship between models designed to be used in momentum and configuration spaces. This relationship is expressed by a unitary transformation. Its consequences for the charge and quadrupole deuteron form factors were investigated in the case of the π-exchange contribution to the NN interaction. For this interaction, the Bonn (Q _b) and Paris models were considered as representative models of momentum and configuration spaces respectively. The above work is extended to the ϱ-exchange contribution on the one hand and to the deuteron magnetic form factor and the form factor for deuteron electrodisintegration near threshold on the other hand. Sensitivity to various inputs is discussed.
