摘要：

The C2/M1 ratio of the electromagnetic N-->Delta(1232) transition, which is important for determining the geometric shape of the nucleon, is shown to be related to the neutron elastic form factor ratio G(C)(n)/G(M)(n). The proposed relation holds with good accuracy for the entire range of momentum transfers where data are available.
