The exchange magnetic form factor of 3He and 3H

Abstract

The contribution to the exchange magnetic form factors of 3He and 3H from two of the important diagrams is calculated for realistic wave functions such as for the Reid potential. It is found that the exchange magnetic moment depends little on the type of wave function used. The q2 dependence for small q2, where q is the photon momentum, shows a spatial extension of the exchange magnetic moment density, due to these terms, that is considerably less than that of the nucleons. This will make the square radius of the total density decrease with a few percent.
