Abstract

The isovector meson exchange currents are investigated on the basis of the product ansatz in the Skyrme model. It is shown that the standard one-pion-exchange currents are correctly reproduced as a limiting approximation to more general expressions derived here. We discuss interesting consequences of the spatially extended structure of the nucleon, which is naturally incorporated in the present treatment. It is also pointed out that there exists a simple analytical relation between the isoscalar exchange current of the Skyrme model and the standard ρπγ exchange current.
