Topological-exchange-current contribution to the deuteron magnetic form factor

· Phys. Rev. Lett.; (United States)
In the chiral soliton (Skyrme) model all isoscalar electromagnetic currents, including the exchange currents in nuclei, are topological and uniquely determined by the current of the individual nucleons. This allows us to obtain a model-independent isoscalar exchange-current operator, which is used to study the magnetic form factor of the deuteron. The structure of the deuteron is incorporated by our evaluating the expectation value of the exchange-current operator with respect to the wave function obtained fom the Paris potential. The magnetic form factor of the deuteron is dominated by the exchange-current contribution and is in agreement with experimental data in the range 0
