Abstract

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 GnC/GnM. The proposed relation holds with good accuracy for the entire range of momentum transfers where data are available.
