Abstract
The proton and neutron magnetic form factors, the axial-vector form factor, and the leading N-..delta.. transition form factor are connected by the nucleon distribution amplitude. If the distribution-amplitude moments obey the QCD sum-rule results, a correlation exists between the neutron magnetic form factor G/sub M//sub n/ and the leading N-..delta.. transition form factor. For existing proposed distribution amplitudes, one or the other of them will be small and the other not. We comment on what available data say.
