Query: Electromagnetic N->Delta transition and neutron form factors   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.
